If I really didn’t do anything wrong why do I feel guilty?

I just can’t seem to win not one time i didn’t get overly cocky or brag to my friends about I talk to this or that girl I just try my best and didn’t work out with any. it was like after I realize that this one girl was mutual but just didn’t want me enough but after that I felt stupid like I was getting to in over my head. wen I know for a fact I wasn’t just wanted that one more than most so I talk to other ones but hoped that one day I could be with her. but it didn’t work out that way at all I don’t see why I feel so guilty to other girls like I did something wrong wen I didn’t. i guess I was trying to wait on a female who wasn’t going to be single anytime soon and I end up the only one single and everyone given up on me.
