Good, the talk went well and he called you after the text. Certainly didn't have to do that. Forget about M. If M were anything to him they would be together by now. He probably knows what M is about and probably, she's just "filler". But that I mean this: When you break up with someone, one of the difficult parts is that you don't talk to that person anymore. So you find a "filler" to fill in those spots. They are there for you to text or call or hang out with. Now, the filler can't do everything, but they help "fill" in the dark spots. I agree with mom. Hold off a bit. You've been this patient, you can be some more. You are doing great DB buddy.
