how do you get over any form of rejection

this has happened to me many times in the past, i try to get to know somebody online, always a girl, i'm honest and speak from the heart and i don't hear from the girl again, then i wonder what i did wrong? did i give off an air of desperation?

i do live alone, get lonely, live with a personality disorder so wonder if i gave off desperation signals and that put the girl off getting to know me? this happened recently on facebook with a woman i liked on my facebook friends.....her last message was a disinterested one sentence reply...and i felt rejected.

i'm a male aged 43 now, and rejection, how do you get over it? i always get devastated by it as i have never managed to find any relationships yet in life.

well online isnt the way to go. a lot of women online are just looking for attention, not the love of their life. its like most dating apps women are surrounded by men, all they need to do is pick and choose who they want to talk to. most of the time, youll get ghosted talking to people online. starting relationships is very complicated and hard now a days.
