I divorced her because she cheated and i really can't stand her.

We have two children who are now adults, so I see no reason why we should make an effort to get along. I'm happily re-married. She just completed her second divorce. Now, through our children, she wants to make nice to me. She cheated and we broke up over it. This was years ago. I've moved on with another woman. She has had several relationships with men that have not worked, apparently. Some of my friends and family think that I should get to know this bitch again. My children, certainly. But I talk to them like the adults that they are (No, I do ont refer to their mother as a bitch, or any other foul name),and tell them that I have no desire to go backwards in life. I tell them that I wish the best for their mother (Not true. I really wish this two-timing peice of cow dung would roll over and die. But I would never say such a thing to them.), but I don't think I can establish any kind of civil relationship with her ever again. I love my new wife. I love my two children. This is more than enough for me. With all these bitter feelings I still have for my ex, isn't it normal for me to have and keep this really fucked up attitude towards her? Am I being normal or what? Is anybody out there in a smilar situation. I'd like to here your input. Male or female.
