Background

I'm a 21 year old male, going to a university as an undergraduate. Last semester I met this girl who happened to be pretty good friends with my Rommate, and we started hanging out collectively as a group (myself, her friend, my suitmates) consistently every weekend.

At first, I wasn't sure if I actually liked her (as a friend), she seemed a little quirky. However as time went by (4 months ish) I started to gain interest in her. At this point we're all really good friends. Not wanting to jeopardize the friendship I didn't mention anything until about a month ago, where I asked her on a date.

Her response "It's not you, it's really not, but I'm already involved with someone and I don't want to be a hoe. In the future it's a possibility"

Great, I left it at that. I had my answer, I was ready to move on. She wasn't interested and that's totally fine, I like being friends with her too.

However, my problem comes from the fact that she does things that might be indicative that she's interested.

1.) I asked her to be my date to a formal, and she said "I would love to". This is after I already had asked her on a date.

2.) I posted a snap story asking if people were interested in running a 5K with me, she contacted me and she wanted to be on my team.

3.) She asked to join a coed soccer team with me.

4.) Occasionally she hints at being jealous of other women I'm with. "Is that your girlfriend?", "Oh my god your texting her in front of me."

None of these things are indicative of anything really, I mean any platonic friend would do what she did . However, a few weeks ago (after I had asked her on a date) I had a party at my house and I invited all the friends.

Towards the end of the night, we were heading to bed and she got in my bed with me in it. From there she started to "cuddle" with me / spoon.

When we woke up, she got changed in front of me.

This is what made me rethink everything and has me confused as fuck. What do I make of this?

I don't text her casually, I believe texting should be only used as a way to set up face to face contact. I'm not needy, I haven't been like "omg I love you blah blah blah" I simply one time, stated my interested, and left it at that. During this time I've been with other women. However the few times I tried making small talk, she doesn't reply.

I occasionally send snapchats to her, not a lot at all, she never answers.

I know she is actually involved with another guy, she talks about how she likes him a lot, and she brings him up often, but I have never seen her with him. She's always with us on the weekends, etc.

Here are my observations/thoughts

  • I am a beta orbiter to her, I'm basically giving away free commitment (cuddling, etc) for no return.
  • She likes the validation I'm giving her, and is using me.
  • I have developed some oneitis and need to stop putting her on a pedestal, she's not special.
  • I was going to escalate when she was in bed with me, but she was pretty drunk.

My question

Is it too late to get with her? I have already started to ghost her, and I planned to until the date of the formal. During the formal I was planning on escalating and going for the kill, and if she denies me or whatever hard next her.

Any thoughts and advice would be helpful.

tl;dr

Want to get with one of my (girl) friends but she said she's involved with someone else. She still continues to try to cuddle with me, change in front of me, and want to hang out with me. Is it too late? Advice?
