I've fallen into the trap that I'm sure many guys have. I like a girl with a boyfriend. I want to first clarify that I don't intend on trying to break them up because I like her. I'm more or less curious as to what girls feel like when they have a boyfriend. Do you flirt with other guys as a friendly gesture? Do you do it to keep your options open, or do you just not flirt with other guys? I've seen all three and I'm curious what exactly goes on through a female's mind with all of them.
What is the right way to interact with a girl you like with a boyfriend? Right now I try not to talk to her because it's too painful. Is there a way to harmlessly interact with her without hitting on her? Like I said, I don't want to be a greedy asshole and actually hit on her because chances are she would hate it. If she didn't hate it, I would feel bad if she started liking me and broke up with him. I just need advice with doing everything possible to keep potential options open without being too assertive.
