I am so sorry this is happening to you. I don't think this only happens with divorce. I have a few friends whose mothers died when they were young adults and all of their fathers totally withdrew from their children then too so it can't all be about the Mom. I don't know why it happens I just know it's fairly common.

Don't think you have done something wrong or that your Mom has done something wrong. Your Dad is a grown man and any decent man should be able to stand on his own 2 feet for his kids. The way I see it, some people are just a mess and do less damage from a distance.
Thank you for your answers (EVERYONE!) but I want to be clear, this is not happening to me--it is my sister. She's been married over 30 years and her DH is walking away from the marriage (and the kids, to an extent!)
My Father passed away 4 yrs. ago and was married to my mom for 50 years--I am very grateful we kids never had to go through what my nephewand nieces are going through.
DSis and BIL were married when I was 11 so I actually feel like this is happening to me (as in as a daughter) in a weird sort of way. I was close to BIL all during my growing up years. He was great to talk with and understood with snitching or laughing. So, I have been quite heartbroken over this divorce for many reasons.
I was a divorce paralegal 25 years and saw this happen quite frequently. Some of the most common reasons are:
1) Parent has a new love interest.
2) One parent has continually bashed the other in front of the kids, to the point kids don't want to see that parent anymore.
3) One parent is making the other so miserable he/she has completely removed themselves from the situation, which includes not seeing the children.
4) One parent makes it so difficult for the other to see the children they just give up.
5) One parent is taking the divorce very hard and emotionally just isn't in a place to be able to see their children.
Well, there ya go. I guess I just thought the new love interest (that he doesn't know I know about) should just take DSis's place, not the kids.
2) Dsis doesn't bash, she still loves him.
3)He does see them, not much and not for long. He does give Dsis $$ for them so he is not being a deadbeat in that respect.
4)2 of the kids are away at school and the other 2 are old enough to see him whenever they want. They want to see him, my Dsis wants him to see them.
5)He wants the divorce so that isn't it. He does seem to struggle at times about the reality of it, I guess. It is strange, in that respect. But maybe being dedicated for 30+ yrs. and then moving on is just tough.
His counselor says things like "You have a new life now." And talks about him not spending as much time with the kids. While time would be split up and all that, I just don't think you stop spending time with your children. Maybe I just don't get this.
I am sorry for those that say they went through this with an ex-spouse. It is really hard to wrap your mind around and like a PP said, you just can't begin to understand it and what they are thinking.
How do the kids do in the future when this type thing happens to you. I have a new understanding of that old saying, "A dead parent is better than an absent parent."
