LOTS AND LOTS OF LUCK!! But you don't need it, you are going to work this thing out all on your own, no luck needed!
But I think if you are feeling underminded and out of control chances are she left the marriage because she wants to exert power and control over you. Maybe she didn't feel like she's had any for years and now it's her turn to show you how it feels....????
If you feel inadequate, depressed and hopeless she probably has feelings of inadequacy too and wants you to feel it as well.
With being and feeling annoyed, she wants attention.
And if you feel wounded with a desire to retaliate, she probably wants a little revenge too.
And I think you think you're confused, but once you figure out how you guys got here, the confusion gets better.
Once I figure out what my H was hearing through all my nagging anc complaining (You're a bad husband, you suck as a father and we're broke because of you) it helped me start doing some real serious DBing. Don't get me wrong, he still does/says things that are confusing, but I'm staying the course and don't dwell on it. I'm really working on Acting as If and Letting It Go. Very hard for me, but I'm trying.
You can do this!
