TL;DR: I've been having sex with a hot girl, I broke frame, things went south, did damage control and now looking for possibility to keep said girl as a plate.

This is a very long post so bear with me, and help a brother out.

Background:

To give you a bit of background on myself, I am a career focused guy at 24 years old. I have average height, but I am good looking with a muscular body (5ft 7 164lbs 14% body fat). I rarely chase girls usually because I am too busy bettering myself and building my future. I just finished a graduate degree in engineering from a world class institution. I have a good group of like-minded friends that respect me and think highly of me as I do of them.

Chelsea:

Cue in Chelsea, Chelsea is a hot girl, HB8 at least. I met her through a friend, and i instantly took notice of her and she of me. I knew she had a boyfriend at the time, I kept cool and didn't chase. We went out together in groups several times, during which I was playful at times and aloof at other. Eventually, Chelsea added me on fb, and we started talking randomly there. Long story short, one night after we go out I fuck Chelsea. This went on for a while until the subject of her BF came up and she said they are on a break since 4 months or something, which I knew was total bullshit. She's been with her boyfriend for 4 years most of them are on long distance, so obviously this HB8 has been riding the cock carousel while her beta BF is hard at work making money to secure their future together. This goes on for a while until her bf figures out what's going on and they break up. After the breakup we continued to fuck for a month, but I could see that things were changing her shit tests increased, and she was always showing me that she has other options. I ignored all that, at the time I had a tinder account, she'd seen it, I had over 30 matches there which I almost never talked to, but still she saw that as a threat she downloaded tinder and started talking to a guy there.

The date:

A week passes she tells me she cant continue like this and she has a date that weekend, i laugh and tell her enjoy. She goes ahead and goes on her date, I go radio silent on her, she flips out. Chelsea has at least 10 orbiters who are madly in love with her including her beta bf. She is not used to being ignored like that. She goes mental especially after seeing picutres of me with another girl on fb. She texts me and asks me to come over, I don't reply. The next date I text her asking her where she was, she replies with "who is this", I immediately shut down her shit test by being sarcastic, and tell her she knows who it is and that I am coming to see her that night.

The Makeup and breaking frame:

I get to her place she was put an angry yet silent front, pining for attention. I talk to her to clarify things, I tell her I thought we wanted to keep this physical only (we had agreed on no relationships before). She basically replies that she's having sex with me and there is no commitment and that I dont care enough for her and that doesn't sit well with her. So we agree that she stops talking to other guys and I stop talking to girls and we date to see if we can have a serious relationship together. This is the major fuck up, here's where my beta bitch came out and where I broke frame. She asks that I delete tinder which I do and she deletes her account as well. We agree not to be physical to think about things in a straight manner. Beta as fuck, I don't know what got into me, I was having fun with her and I guess my beta mentality kicked in and I feared losing her.

The Fallout:

This went on for a month, we were still fucking in contrast to what we agreed on but not as frequently. During this month, I felt that was getting more dependent on her, since I was in the mentality that I will give this relationship possibility and honest shot, especially that I got rid of other options hence losing the "abundance mentality". Meanwhile she sensed this and she felt empowered, she went back to talking to other guys. And would say things that "i am training myself not to miss you", I saw the red flags and toned down my attentions. I knew at this point that I fucked myself over. Long story short she makes up a reason to fight, because I went out with a friend of mine who i havent seen for a month, while she was sick. And she says she's done. At this point i cut my losses and don't pursue, even though I wanted to because I developed oneites to this hot chick, and lost my abundance mentality.

Damage Control:

I went radio silent. Four days later she is sucking the guys dick that she talked to on tinder. I knew about that through friends, I held frame and didnt contact her. The next week, she texts me sending holiday greetings, i wait a bit and reply with a holiday greeting. That same night, I hosted a party at my place, I invited a lot of people and of course I didn't invite her, she sees the pictures online there were several pics of me swarmed with girls. She flips, she goes on another date with her tinder man and posts pics online, trying to get a response out of me which of course she didn't get. Eventually, she calls wanting to clear things up. I basically tell her we had a good run it was fun, and there's no moving forward from there because she didnt honor her commitment, conversation ends. An hour or two later she sends a length text saying she did honor the commitment and did nothing behind my back, and she really hopes we remain friends. To which I tersely reply, saying that I know what her character is like and that I don't want to argue further, and that we're friends. (my nice way of saying f off).

Reclaiming Some of the lost Power:

I don't contact Chelsea after this, I move on and continue life as usual, going out with friends and focusing on my happiness again. In a little over week, Chelsea has a fallout with a common friend and it get very very bad. None of my friends wanted to deal with the bullshit and try to keep this two girls from killing each other. So I stepped up and texted her saying them shit about how we're all friends and that I wont allow any of this to continue. She replies promptly and asks if she can call, I oblige. We talk and she tells her version of the story, I diffuse the tension and that was that. Later that night, at around 3 am, I receive a lengthy text from Chelsea, saying how she is thinking about me, and that I am very special to her, that she never meant to hurt me and she is sorry if she did. She said she really wanted us to remain friends, but she understands if I want nothing of it. And concluded with a "good night :*"

Reaction:

i haven't replied to her yet, I am not sure how to reply. Obviously, I am not interested in a friendship, I want to plate her for several reasons. Firs, I enjoy having sex with her. Second, I want to practice strengthening my frame. Third, I want to integrate the TRP mentality into my identity by practice hence the need of a plate. I have been learning about TRP for the past year or so and it's obvious I still have a lot to learn otherwise I wouldnt be in the current situation I am in.

So my question to you guys is, what would be the best strategy to plate Chelsea, now that she's the one pursuing and pining for my attention, I gained some leverage back. How should I reply/proceed?
