Question for older folks!! i need your opinions?

I'm 37 with two sons ages 7 and 14. my oldest son has Autism. I've been divorced since 2003 but he and i tried to make some sort of a family life still for our son, the 7 year old and my 14 year old. he was a truck driver and only home once a month. so it was ok i guess to put up with for my sons sake. Finally i had to tell him to not come here to stay anymore. it was not good when he came here after a while. Now he doesn't come to see his son at all. And my oldest son with autism, thinks he is his father as well. i was with him for 8 years. so both of my sons are missing him. He got married 3 weeks after we called it quits for good. he's been in jail for hitting her already. since the day we called it quits, he has never come back to see the boys. its been a year this last july. Since then, i've pretty much found men to be disgusting to me. not that im liking girls! but i just have no desire to have a man in my life. the thought makes me feel disgusted. do ya think this is normal or what? i don't want to become bitter and cynical against men, but really, right now i think they are all pigs. i can't ever remember feeling this way before.
