I want to hook up with a girl who has a boyfriend
I'm not really sure what you expect to come from hooking up with a taken woman?
I think she's looking for something long term and I'm not going to give her any serious commitment. I just want to hook up with her.
It's immoral to hook up with a girl who already has a bf. You'll destroy their relationship and they both would end up getting hurt.
Yeah but I'm going to do it a way that she falls for me and leaves him.
You just said you don't want to be committed to her, but you are willing to destroy her relationship? Not only do I not think that it would work, but it would make you seem like a terrible person. Do you want to look bad to others?
