I saw this on my sidebar a few minutes ago and had to pause and comment.
I don't care HOW bad his marriage was, he was married. And she was still a teenage fangirl chasing after him. Both of them are in the wrong, but she is moreso, because anyone who knowingly chases after a married man, and doesn't care about the fact that there's someone at home waiting for him? Deserves whatever hate she gets.
Furthermore, what about Alicia? She's put up with him for a period of years. She's put up with all of his faults, his shortcomings, and all the other bullshit that comes with being married to someone "famous". She is legally bound to this man, and there's a LOT of red tape and paperwork to go through to sever that. Who are we to excuse Mikey because "his marriage was terrible". That's no excuse to go fucking someone else behind her back. Be a man, grow a set, and file for divorce. Don't sneak around and humiliate your wife just because you're a wimp.
