It's funny because I feel the same way about the women on this board. Such caring people.
I agree with you, codependency is tricky especially when you have kids. It makes it hard to maintain your own identity. I think the key is finding a balance. Maybe if its only a few hours a week to pursue things that enrich your life. In my case, I would make my entire life about my family. I didn't do things with friends, I wanted to spend my free time with WAW and our kids doing things together. To me, that was normal. But I wasn't balanced. I didn't do things just for me. Perhaps WAW just got bored with me.
In my relationship we definitely got in a rut. We both worked and then came home at the end of the day. I would help her daughter with her homework while she cooked dinner. It was like that every day.
Then we would clean up, watch a little tv and then go to bed. Rinse, wash, repeat.
