I got pretty good at hooking up with random girls but I feel kind of empty. I was in a long distance relationships with a girl from my high school who treated me like shit, was an alcoholic, was not attractive, etc , etc, bad life choice. I broke up with her and she did not really care. I was feeling really depressed, joined a frat, started lifting, etc etc , got bigger, got better haircuts. I started hooking up with a ton of girls after pledging ended and it was really fun because I have never really been great at that stuff before. Now I feel like it has become stupid as fuck and empty. These girls dont really care about me and as hard as I try to not let anything faze me or not be dependent on girls for happiness I would really like someone to connect with on some level. All I can do to hookup with girls is act like an overly confident douche, and it works but it feels bad and there is no connection. I know this is super cliche but I am afraid to act like myself because that has never been attractive to girls, but acting like this overly confident twat , which works, is not me at all but it does at least get something. What should I do?
