I need some advice.

About three weeks ago I started seeing this girl and we really hit it off. Since then I've seen her maybe seven or eight times. Every time we're physically intimate. A few nights ago, I asked her where this was going for her, and she said she wanted to be dating but not in a relationship. I'm okay with this, but since I asked I'm not sure if she believes me. Things got kind of awkward for like half and hour, but then we were right back into the swing of things, and the date ended well.

Two days later I text her asking if she wants to talk that night. She says no, but suggests IMing instead. She seems more distant.

What did I do wrong? And (how) can I fix it? I feel like she's lost interest in me and I want to renew that interest if I can.

Not really answering this question but man you have a bad case of oneitis go and game some other girls and you won't care so much about this one seems like your swimming or drowning with only her

You're exactly right, man. Thanks for the encouragement. That's exactly what I'm going to do.

No problem man I had this problem all the way until I started college
