Heres a summary:
-Had a date with this girl on Pof
-Went to a quiet bar and talked for about 2 hours. Conversation flowed well, she laugh at everything I say, kino worked well. Mentions that she does not usually talk this much. Tried to Kclose but didnt happen
-Went to get ice cream after. She paid for me
-As we left, we gave each other a hug but I didn't offer to walk her home

No follow up text or call from either side. 3 days later i shot a what's up text, and teasing her about something from our convo. No response. Its been 4 days and I'm guessing it's most likely over. Anything else I can do here, anyway to recover?

She's probably not interested.

If you want my opinion. Your best move on this would be to find out why, so you can improve your game. You don't need to be PUA about it either, cuz more than likely she's not interested anyway.

I've done this, and it's improved my game a lot.

I would wait like 3 weeks to ask why because you never know if she's busy or if it may just be a test. Wait for her and never force things.

so very uninterested.

What's your problem dude?

She's very uninterested in you.

I'm not sure how much more clear that can be.

Deepest apologies for not sugar coating that for you.

Thought you meant you were uninterested in the guys problem. I agree with you.
