TL;DR: Hooked up with "party girl" i've known for 9 years. Had a great night, both had a lot of fun. Tried to hang out with her a couple times with no luck. But she continues to respond to my texts and says she wants to hang out. What do I do?

Situation:
Okay first off, both of us are now in our senior year of college, but have been going to school with each other since the 7th grade. We were never really friends, just knew of each other, had some mutual friends and it wasn't until this summer that I started talking to her more.

The girl is basically a party girl. She goes to concerts all the time, enjoys recreational drug use and hasn't been in a serious relationship. I am somewhat similar, I went to a lot of concerts and enjoy using drugs recreationally, which is sort of what we started talking about.

Anyways, we hung out one night, went to a party together, had a great time, and I really established some rapport with her. I messed up because I thought I should show some social proof, so I somewhat ignored her for a bit and talked to a ton of different people, but then lost her at one point, and left the party.

Next night I invited her over and we hung out at my place. At one point we started talking about sexual experiences, she tells me sometimes she feels obligated to have sex even if she doesn't want to, but she really enjoys having it. I talked to her about why she hasn't been in a serious relationship and she said she usually doesn't stick around long enough for anything to develop. Other things are said about experiences, and we eventually end up hooking up. It was great, we actually spent a few hours just cuddling, talking with each other and really connecting. I really enjoyed it. At one point I joked about it being a ONS and she got really offended. She also said she really likes me and didn't consider me a random hookup, and she still wants to hang out with me. Also, we were both sober when we hooked up.

I waited a couple days after that night to try and hang out again. Invited her canoeing later that week, and she seemed excited at first and definitely wanted to go. But a day before she texted me saying she forgot she had a study group that night so she can't go but said she wants to go another time and I should text her about it.

I didn't text her for a while, was busy with other girls. Texted her one evening, started talking about things. She would literally send 3 texts for one of mine. Seemed interested. She would reply within 5-10 minutes over the course of a couple hours. Then told her I was hanging out with some friends at my place and she should come over. No response. Then the next day I woke up to a text from her saying she felt bad, she was just seeing the text but we should definitely hang out/party again sometime soon, like next week or weekend.

Question:
I haven't responded. I'm not sure if she is actually interested in seeing me again or is just being nice by responding to my texts. We are both busy people, and each time I have asked her to hang out she has given a legit excuse as to why she can't. I think my timing may just be off and I should make plans with her a few days in advanced. Just I'm not sure whats the best course of action. Wait for her to text me? She doesn't seem like the kinda girl to go seeking guys, so I feel like I should be the one making the plans. I'm not looking for anything serious, just hoping to turn this into a regular FWB.

Bump.

Hey mate!

I think you have two options: You find out yourself with plain honesty if she is interested or not or you let time do the work for you.

First option: just text her that you really liked what happened that night. Tell her that you would like to do that more without any strings attached. It is ballsy but in this situation, it is what i would do. You have had sex already, she isnt going to think any less of you because you want more. There might be a chance that she does want a LTR, but in that case, i think that you being honest here is only fair to her.

second option: time. Invite her a couple of times more, perhaps instead of texts, call her. if every time is a bad time, end with: you are hard to get hold of. You know what, let me know when you got time and ill see if i am available then. Then i wouldnt make any more contact. If she really wants to meet up again, she will.

Words are only words, you should let her actions speak.

cheers and good luck!

Bad move to invite her over when your buddies were there. You've already f-closed this girl, so why waste time with your buddies? She seems keen so you need to stay physical with her 1-on-1, or she will think you just want to be friends. Also don't spend too much time going around bars with her where other guys will hit on her. If she is a party girl, there are other places you can take her which will satisfy her free spirit, such as music festivals and theme parks.
