Please bear in mind I probably make a few clear mistakes in the following story (I hadn't read about TRP principles until a few days ago). But what should I do from now? Any thoughts greatly appreciated.

I match with a girl who says she wants "FWB for LT". Went on a first date with her which went fine, I made her laugh etc. We texted a bit and the following weekend she said she had a couple of dates lined up with other guys. I left her on read and deleted her chat. I didn't want to compete and wanted to show I didn't care. I forgot about her.

A week later she texts out of the blue asking when we could see each other again (classic - charming in person, distant the rest of the time always works).

We meet up, get drunk, she's talking dirty to me. I invite her back to mine. We do stuff but we don't have sex (she told me she had and STD and I was a bit hesitant, we were both understanding and nice about it though). She really wanted to but I just couldn't do it with a girl so quickly. She keeps telling me how she's a submissive, she likes having her hair pulled, strangled etc. I just acknowledge it. On the Sunday she needs to cancel going out for a meal because she's exhausted (I suspect it's because of sex with someone else but don't care that much).

We meet up the next week, everything's going great, making her laugh etc. I bring up that the other girl I was dating had to break it off because she moved away for work (so now she knows I have no other plates). Then she brings up that she can't spend too much money because the next day she's got plans. I ask what they are, she says I don't want to know, I get curious and ask, she says she's arranged to have a sex date with one of her regulars.

The fact she's doing this the next day after me kind of throws me off, I stop being funny and emotionally committed to the date. I try not to look upset but I feel a kind of deep sadness. She asks me if I'm upset and I just say it's weird to know. She tells me she's not looking for commitment, she wants to explore, she likes seeing me, she says it's important to be open. She strongly recommends I date other girls at the same time. She says she was abused by her first boyfriend and she's only become this promiscuous in the last year. She then lays it all out, after I ask, and says she had to cancel the meal a few days ago because she was recovering from the adrenaline drop of BDSM sex with her other regular.

She was sweet enough about it. I said to her even with an FWB I still want the girl to be looked after, which is hard to do when I know she's having BDSM sex with another guy. She says she can look after herself, I reply that I know she can, but it feels like the point of being a man (sorry if that sounds sexist but whatever, I say). She says fair enough. She says she expects me to get tested for STDs regularly (which kind of implies she wants to have sex with me). I say I want to see her again, but she needs to arrange the dates from now on because I don't want to be the one trying to fit into her schedule. She agrees. At this point I'm still feeling kinda weird/sad about knowing all this info. We say goodbye and she kisses me on the cheek. She texts immediately, asking if I got back okay, saying she got back okay, was super sweet saying it was lovely to see me again and she wants to meet up again to buy me birthday drinks on Tuesday, I say okay.

The morning after her arranged sex date, before she's got home, she texts me asking how I am, being sweet again. I say "how's it going", she says "it was alright", and I'm again kind of weirded out that she's talking about seeing her other regular with me directly.

I have to postpone the Tuesday meet because I forgot I had plans. She suggests the following Tuesday, I then ask if she's free in the weekend but she says no, sorry. (I'm annoyed at myself for asking this as I told myself I wouldn't chase her, I gave myself away by asking this). So I'm meeting her on Tuesday. I haven't initiated contact since, although she wished me happy birthday on Wednesday. Currently I'm not sure if she's being quiet with me or I'm being quiet with her - maybe both.

So that's the current situation. My current strategy is to meet up with her, be nice and charming and fun, maybe go for drinks, maybe kiss her. But I'm only going to invite her back to mine if she hints at it. And I'm not going to try to plan future dates, per our agreement.

I want to experiment and see this play out out of curiosity. I'm going to pursue other girls, but I want her to be more interested in me and stay at mine again. She's been with the other guys 3 weekends in a row. As the new guy I'm 3rd in her priority list at best. How do I make her more interested so she sees me more often? Is my strategy a good one? Thanks for reading.
