So I just asked a girl out, she said "should have told you I have a boyfriend, I don't have a problem with going out with you through, if that's not a problem for you"

I replied "if he doesn't have a problem why would I?

And she said "ok, I just don't know your intentions so that's why I told you"

So I'm going out, tips, what to expect, or should I take it as a no?
