My thoughts are that if her marriage to an aspie is so horrible, GET A FUCKING DIVORCE and MOVE ON! Do herself and him a favor and end the charade...
This has been suggested to the members of that site in the past by a partner who liked her Aspie. I think she got banned for suggesting it... or at least got flamed.
Why am I NOT surprised! 
See, if they got out of the relationship, they wouldn't be able to feel quite so much self pity unless of course, the courts saw them for what they are (pathetic whining losers) and awarded a fair property settlement and custody arrangement for the kids if there are any. They cannot or will not see that there is a hell of a lot of difference between venting and then doing something to improve the situation or endlessly whinging and whining because they got a bum deal out of life.
Do they ever think how unhappy they themselves might make their families? Noooo! That would take intelligence and the ability to look into themselves and realise what they might be doing that's ineffective eg. trying to force their partner or children to change, wasting their time on ineffective therapies, expecting to constantly be treated like a princess....and so on.
