Wow, so many loaded questions! Hind sight is a fantastic although useless thing, isn't it? It's very apparent that you and your ex and MANY MANY other couples together or divorced (me included) have DRAMATICALLY different values, priorities, etc....there is no simple explanation for how such two different worlds got together in the first place. My exhusband (still really weird saying that 3 years later) had a miserable childhood, both parents especially his mom had serious drinking problems...and yet when sober and not sick as well, he is a decent person. I felt like I could show him the beauty in life, in family. Whether he's sober or not, I am the caretaker in the family, he does not feel, or at least behave in such a manner that would suggest he feels like I do about our kids. He will be mad at me for eternity for leaving. In his mind, on a whim, I took his house, his kids, his paycheck, etc., in reality he traded all those things for another case of beer. That aside, he STILL has three amazing kids, he STILL has unlimited access to them, but he will not accept the idea that HE has to foster his OWN relationship with his children, it's still not apparent to him that he didn't REALLY have a close thing with them when we were together, and now I'm no longer the go-between, he doesn't even know them, and blames ME for it. When in fact there are opportunities everywhere for him to be close to them. It's very sad for him........not to suggest that they are completely uneffected but they have a REALLY nice life without him....Anyway, yes it is a mental illness for MY OWN ex, for some I believe it's just a difference in upbringing........Many men who are going to work and paying the mortgage and showing up at the occasional tball game may feel they really ARE involved. I am old fashioned in a lot of ways....it's lucky for your son that his MOM is the caregiver, that mom feels a strong sense of the importance of family...even in this day when most moms have careers, it's still mom holding it all together (sweeping generalization here), it is, after all, why WE'RE still having the babies. Hope this helps, I understand your sense of, oh well, this is the way it is....but it could be SO much better....Hope you are taking care of yourself mom.
