My parents were married for 23 years, and had a bad divorce. People don't just get over it in a certain time period. They've been divorced 3.5 years and seperated since I was 14 and I'm 21 now. I think your mom probably needs to talk to a therapist to get pastt her anger, and to start really living again.

I know it may seem she doesn't care about you, but sometimes we get so enveloped in our problems we forget others are suffering too.
