I've been hanging out with this girl on and off for some time now. I've gotten feeling in the past from her that she likes me, but I've already screwed up my chances(if any) twice! I just wish I could tell her how I feel about her; but I have a feeling the opportunity to do so is completely gone :/ any advice?
The only thing you can do is tell her how you feel. And give her a chance to tell you how she feels. And if you are on the same page go from there.
But if you chose to not say anything things between you two are going to remain the same.
If anyone else has advice to add to this please do so.
