<human>: Can you condense the text into three sentences or less?

Im a college aged male coming from a divorced family. I spent most of the time with my dad, and see my mom on occasion. Originally that was just how things were divided up but the past few years she's been rather high maintenance, and kind of hard to be around. She gets incredibly defensive when someone tries to bring something up to her, or as she puts it, when she feels someone's attacking her. 

Anyways, that's the pretext. This last year, I've noticed things between my mother and father have been getting worse. Most of my life they tried to be relatively civil between each other, at least around me, but the dam has been cracking since I left for college. 

I've been trying to get them back to the "Civil" state of mind but it seems hopeless. As I'm getting older, I don't really want presents for christmas, but I enjoy having my parents together in the same room.

It's been made clear to me this year, that my mother has absolutely no interest in coming over anymore, she believes that my entire family hates her, (my dad...maybe but not the rest of em). I guess she thinks she doesn't have to humor me about wanting to come over anymore. 

Sorry for the long post,
<bot>: My mother want to come to christmas because she feels that being around my family is toxic, even for 15 minutes, once a year.
