Well she's always been a great mom, and has dedicated all her time to our kids. Just a couple of things:
1) Our 4th child was a surprise, and I know that caused additional stress in our relationship but also on her life goals (we were talking about going back to school, I wanted to go on a trip to Paris with her, etc.)
2) The oldest kid who is now out of highschool and her, rebelled against her. I don't know if she blames me a bit for it, but I'm sure she thinks I didn't back her up enough in that conflict, so there's resentment there. She also feels like she failed our oldest child, she didn't but that's how she feels
3) The other day she told me about the "weekend off". She also told me that, "You can let the kids do whatever they want with you, but they're not going to disrupt my FLOW" (!?!?) She was referring to their last minute demands, and driving around all over the place. She's had enough, and I get it, but the way she expresses it is a bit disturbing. She did open up a lot to talk about that that weekend.
She also wants me to back her up with the kids which hast put me in uncomfortable circumstances:
a) She was arguing with one of the girls, who took offense to something she said, I backed my W up. My daughter then told me "I felt like you took mom's side against me because you want to be nice to her" (ouch!)
b) Another time she was having another argument with another kid, I stayed quiet. She then went to scream at me because I didn't back her up. I told her I didn't know the full situation and decided to stay quiet, not that I was contradicting her.
