I used to feel more confidant than the average person. A year and a half ago my girlfriend of 7 years cheated on me and I've been slowly building myself up as a better person. For the most part I feel like I'm back to my old self but I've recently tried dating recently and I find the slightest rejection hits me hard. I.e I matched with a girl on Hinge. We are messaging back playfully and it was awesome. I made a not so great joke and then her replies started taking longer. I feel sick, I felt like shit and I know it's fucking dumb. I feel anxious. Maybe we will unmatch tomorrow and I'll be fine! Like consciously I know how dumb it is. On a subconscious level though I'm still hurting and must have some issues. I think I want validation from a girl who I really respect the hell out of and admire. So if we have a date and it doesn't work out - I'm totally cool with it - I'm fully expecting to date 20, 30, whatever amount of girls before I settle down. But there's just something wrong with me and maybe it's my self esteem at an unconscious level? Maybe it's just fragile?

Any advice on how to fix/strengthen?
