So I was out with some friends, and one of the girls I've been seeing couldn't make it. We were flirting back and forth over text messaging, then I kinda let that drop and concentrated on hanging out with my friends.

Unbeknownst to me, one of my friends is texting the girl and apparently told her about me dating someone else. This "friend" is actually attracted to me herself, but married. I called my girl back and we talked, it turns out that my friend has been talking to the girl a lot telling her both good and bad things about me. Sometimes supporting me, other times trying to stir up the pot and cause trouble...

By the end of the night I got a text from the girl saying that my friend had been texting her all night, but she "doesn't have problems with me hanging out with other girls but doesn't like drama."

I called her on the way home and we talked it out, the only thing I'm not sure I handled well is she'd say something like she wasn't sure where we were going yet anyway and pause. I didn't know if telling her I'd like to move forward would be good, or if that would convey too much interest too early (we've had 3 dates and hung out a bit before that.) I just tried to agree with her that it was just really early to be thinking about that stuff. (Honestly I am thinking about it and I think I do want to work towards a relationship with this girl.)

But the other question is, what do I do about my friend?

Anyone?
