"The problem is she has often ambushed me on the phone, it starts off innocent and then turns ugly and ends up with the interrupting, me being quiet while she rails, or a few times me just hanging up and then I'm accused of being the immature one."
The problem is that you haven't learned anything from your interactions. She doesn't "ambush" you. It's the way you've interpreted and reacted to things. Even now when you interact with her, you're too afraid to talk to her on the phone. If you can't do that, how do you plan to interact with her in person? Start talking to her on the phone and get a dialogue going.
"First, AnotherStander & Tallula, thanks for the support. I appreciate it much more than the "give up and move on" attitude I get sometimes. "
This was a cheap shot and shows that you haven't really understood what many have been telling you.
First of all you're not M'd to her. She's your GF so the dynamic is different.
Second, those aren't your biological kids. Unfortunately that's the harsh reality. I'm sure you made an impact in their lives, but I believe you said the OM was her ex? That's a strong bond.
Third, you are still obsessing over her which isn't doing you any good. You're going through analysis paralysis where you analyze every move she makes that you are becoming unsure of what to do yourself. Not good at all.
Do I think you can get her back? Absolutely. BUT you are going to have to change your thinking and to a certain degree really let her go. That's the ONLY thing you haven't done. Everything you are doing hasn't worked. The only time you got a 'response' is when you actually listened to our advice and cleaned your place up. And we told you to do that for you and not for her.
You would be farther along if you really listened to what we were saying rather than following your interpretation of what we're saying.
