Been there, done that. I was married to a man(boy) who turned out to be autistic, specifically Aspergers Syndrome. I figured this out a little late, when I was divorcing him. I had lots of physical problems that caused me to gain weight steadily throughout our five year marriage. I decided to have gastric bypass surgery to combat the problem and help with my health problems. He was not supportive of my decision, apparently he was a "chubby chaser" at heart.
He immediately began surfing the internet for fat chicks after I fell asleep at night. He was a computer network genius, but was totally inept at covering his trail on our home computer, very typical of someone with Aspergers. I was able to logon with his ID and password and follow all his activity. He was most interested in women 500lbs and up. I collected documentation for a couple of months before calling a "family" meeting with his parents and mine. I had copies of instant messages, emails, and naked photos of women he had been chatting up and starting to date. He even brought one to our town to find an apartment for the two of them. His father was incensed at his son, and could not believe he was chasing these "circus freaks."
As soon as I realized what he was doing, and that he was totally unsupportive of my surgery, I immediately knew I was headed for divorce court. I didn't want anything to do with him, but I also didn't want anyone hooking up with him either. Why should he get away with treating me like crap, and walk away with somebody else already lined up to step right into my spot. Every time I located a new one of my husband's targets, I filled them in on his shenanigans. He had told every one a different sob story, i.e. he was a widower, he was separated, he was divorced...you name it. The only thing that kept me going during that time was to vex him at every turn. Not to mention, he kept telling me he wanted to work things out. What a load of crap. I was so hurt and depressed that he was effectively dropping me like a hot potato, especially because I was trying to improve my health, I wasn't going to let him get away pain-free. It's bad enough to be dumped, but it is worse to add insult to injury.
Just my two cents worth,
