Need advice for a WW who left Part 3

[dwh15]

Well, just had a nasty phone convo with WW. I probably shouldn't have even answered but I did. Started off pleasant and she asked me what I was doing tonight. I mentioned I was taking her nephews out to dinner and she lost it. Wanted to know why I couldn't help her financially. Really laying on the pity party about how she had to ask OM for money just to rent bowling shoes for the kids tonight. I said "what's wrong with that. You're with him now. He should be helping you."

Then she got into how I made promises a few months ago that I would help her financially, and kept accusing me of breaking my promises. Well, that set me over the edge. And I was like serious, you're going to throw stones at me. You mean like the promises you made the day you took your wedding vows? She replied, "serious, you wanna go there?" Then it kept escalating, and I told her I didn't have to explain my financial situation to her. She said, "no, not to me". When I asked what that meant, she just repeated. Finally, I told her that I did plan on helping her with food money for kids when I had regular paychecks coming in, but that I was being nice and had no obligation to give her a dime. The last thing she said was "no, you don't have to give me a dime...yet" and hung up.

So she was obviously threatening that she plans to file. I almost called her back but then figured what's the point. There's no way to win. If I cave and give her what she wants, I'm a doormat. If I don't, then I'm a jerk. Right now, I really don't know if I even want to try anymore. She is so wrapped up in her own selfish world that I don't see her ever coming out of it. There's no consideration for me or my feelings and the damage she has done - it's all about her. So I am prepared for the coming D paperwork, and will be using my accumulated child logs to go after as much custody as I can get. It's not in the spirit of being mean, but I really don't trust my W to have the best interests of the kids at heart right now, over her own selfish concerns.

Feeling so frustrated, and really, just done with the whole situation.
