(Pic unrelated) I've been in a bad luck streak regarding love, falling for people that wasn't really healthy.

Had a girlfriend and we dated for over a year, ended relationship for some issues and because she was going to to leave the state, but we kept dating and fooling around, we kept feelings and stuff. 2 months after she left she made out with some dude and lied to me, even when we promised to be honest about it, I found out months later by accident and I cut everything off with her, ending even friendship.

After that I took a break of meeting people, then I met a girl who liked me pretty quick, dated for a while, fooled around and then she dropped me because she was "confused", never talked again.

Not blaming them, it must be me and I want some tips on what should I improve to stop this trend on me. I'm not desperate on love, sex or attention, just want to improve myself.
