So I met a girl online, things were going pretty well. We ended up making out, and we got handsy with each other.

She told me she likes it, but wanted to make clear that she wasn't gonna go further and that she wanted to wait for that.

I've been down this road before, where a girl made me wait but slept with others and that made me feel extremely unattractive and undesired, so I told her, that's fine, but I did ask her if she's sleeping with anyone else.

She got upset and asked me why I'm asking that. I told her that while I'm fine with waiting, I'm not gonna date her if she was sleeping with others while waiting with me.

She got even more upset and told me "that's none of your fucking business"

Safe to say that I won't get another date.

Was I the asshole here? Is it unreasonable to expect her to not sleep with others if she's actively waiting for sex with me?
