Wow .. I should probably remain silent, but won't ..
I was married to a man for 15 years that did absolutely NOTHING with me or our children. He worked "provided a roof over our heads" (I worked full time also
) .. and thought that was all he needed to do.
For years the kids would ask "Why doesn't daddy ever go to ____________ with us .. " (insert: vacation, park, store, grandma's, zoo ..whatever) Then they stopped asking.
I got them up, fed them, took them to school, went to work, fixed them dinner, put them to bed .. etc, while he sat there proud that he "provided a roof over our heads".
Eventually, I quit prompting them to say goodnite to daddy .. or goodbye to daddy on the way out the door to school .. etc. He never seemed to notice. But he worked hard, every day, "providing a roof over our heads."
Many times I approached him about our relationship .. or lack of one .. and his un-involvement in the family. He would tell me that I was hormonal or such.
So after 15 years, I told him that he would HAVE to put more effort into the girls, and his FAMILY or things were going to change. He refused and said he wasn't going to change, so he would just leave.
He did .. and then was VERY surprised several weeks later when he asked if I wanted to re-consider and I told him no. What he didn't understand was that he THOUGHT I said that I was tired of doing everything by MYSELF .. and now that I was "alone" .. I was still doing everything myself. BUT ... the EXPECTATION was different. There wasn't "another half" that wasn't participating.. It was just me .. and I found a new ambition.
One of the most telling things was when his mother told me months later how upset he was to lose his family. She said to me "You will never know how much his family meant to him."
I said to her "How sad is THAT?!?! That his WIFE will never know how much his family meant to him."
We are divorced now, and probably communicate better now than we ever did when we were married. AND he's a much better father now.. another subject.
Relationships are work .. but it takes TWO.
I know EXACTLY where you are .. and I'm sorry you're going through this ....
