Well, my best friend is one of my exes so, It worked out pretty well there. other than that. no other experience. Chill out woman, the right person will come along when you arent looking or expecting it. It happened to me.
like KaraLynn said, there's a weird phase usually.
i've been in two serious relationships. after the first, there was a huge weird phase. but since we worked together, we still had to see each other. eventually, things became cool between us and we'd chill after work. since i quit, i don't see her anymore though.
and the second ex, we tried to be friends, and it kinda worked for a while, but then things went to shit. we hadn't spoken for 2 months, but we just started talking last week, and things are ok.
