So you reached out 2 days ago and she never responded?
So you never set the fun date as suggested?
You never went for the kiss?
So yes she could have met someone else though doubtful. She could have decided she doesn’t need another friend. You could have done something to make her decide you are not BF material.
Mach I’m going to be honest with you. You are all over the board. You are not ready to date and you are half a$$ing it anyways.
IMO you should be working on making friends, finding hobbies and self improvement.
What happened to the other two girls you were talking too?
