Kind of nonexistent love life

I’ve never been in a real relationship before. At first, I liked this one girl for years and never got the guts to say it, but then when we finally said it, I didn’t know what to do and she left me within three months. I’m currently in a semi-relationship right now (it’s complicated) and things are pretty good right now. I’m learning a lot. Case in point, I want a real relationship, but I’ve never done it before and I’m a little scared of it. My mind just goes crazy when I think about this stuff. I’m still holding on though, I think I’ll work this current relationship out. But if I can’t, I’m sure I’ll find someone for me.
