I've had that worst experiences with friends. My last best friend were super close until she met her boyfriend. Then she forgot all about me and used me. She didn't care about me anymore after she fell in love with her boyfriend but kept still inviting me to her place to keep her company. I got her a Christmas gift while she didn't get me anything. I bought her a Thanksgiving dinner, she didn't even bother looking at me while she said thanks. I was the only one putting in all the effort going to her house to hangout while she didn't bother lifting a finger. Another friend of mine , cut me off after I stopped helping him with his investment. Ghosted me after I stopped investing in his shit. We spoked daily for two years and had a super close relationship where he knew almost everything about me. I was his only friend. He was also my only friend.
Now I'm trying to get back out there to meet new friends. Its so hard to make new friends. I would go out to social events then later try to create a chance to meet up with them again, very rarely would we ever meet again. They would make up all sorts of excuses, cancel on me last minute. Every time I try to talk to a coworker, it seems as if they are talking to me to kill time rather than to actually get to know me. I'm not expecting to meet my next bestie at work but its good to at least have some sort of a genuine connection right? Nothing feels genuine about my interactions with anyone. When I try to talk to my coworkers, our conversations wouldn't last or they're always on the phone talking or texting someone else.
