Why am I like this?

Zelda

I’ve only ever been in one relationship (I’m only 18, almost 19) and it didn’t go very well. There was a lot of emotional abuse and it was very toxic. I’ve been single since and i feel perfectly fine with it. I’m talking to this guy that’s super sweet and we have so much in common. He’s NOTHING like my ex. He asked what “are we” and I didn’t know how to answer. Every single time I get into a situation that almost turns into a relationship I start to panic and feel super unhappy and trapped. One moment I’ll feel fine and can’t wait to see him, but the next I start thinking about being in a relationship and I freak out and want nothing to do with him. I don’t know what’s wrong with me. I find it very difficult to see me being with someone,ever. :(
