So there's this HB8 I've been talking to for a while that I met in one of my summer school classes at college. There was a mutual attraction that pretty much began since the first day of class. She's 20 and I'm 23. Since then, we have been on a couple dates. I played it cool and called her every once in a while because I knew she was in a relationship with another guy. A couple weeks ago she calls me saying how she wants to get together and hang out. We get together and meet up at a local cafe just off of campus. She reveals to me that night that she just recently broke up with her boyfriend and from the beginning she displayed all the obvious signs that she is interested, like the doggy dinner bowl look, IOI and loads of kino.

In the back of my mind I think she's on the rebound and I'm just her emotional and physical security blanket. Which doesn't really bother me. That night I take her back to my place and we passionately makeout for a while. A couple of days later I decide to contact her again and schedule another date a few days later. We agree to dinner at my place where I cook her a spaghetti dinner. Things are going great from the onset and she interacts with me throughout the night like we are a couple. That night I sleep with her and things couldn't have been better. She had a good time and I definitely had a good time. She leaves my house telling me how much fun she had and wants to do it again. So again I wait two days to contact her again.

This is where I think I screwed up. I called her again attempting to schedule another hang out. Friday night she celebrated her sister's birthday and couldn't hang out. The next night I text her this time asking is she wants to go to a party. She turns down my offer and tells me she's waking up early to go snowboarding. Two days later I call her again and this time she doesn't answer and so I leave a message. Three days pass and I still don't hear back from her. I throw one more text at her gauging her reaction, and I text her, "I just saw your twin and she's just like you! Weird thing was that she wouldn't stop flirting with me. I told her to get lost... haha."

Her response was: "Haha no way! That's kinda funny."

It wasn't exactly the response I was looking for, but the conversation deteriorated soon after wards.

Since then, I've talked to her once. She's still really friendly with me but I don't feel the IOI like before. I get the impression that she may have patched things up with her ex or I screwed things up by being too needy.

What's the best way to determine this? Should I just flat out ask her what's the deal with the last guy she dated?

Can I salvage this and maybe turn this around to how it was before? What could I have done differently after sleeping with her?

Any input would be great.
