Is he lying about leaving his wife?

Me and my "boyfriend" have been together for a year and a half, he is married. I knew this and i continued to peruse the relationship anyways, which i know was a bad move. But after his wife found out about us she was pretty distraught and from what i umed was going to divorce him. My bf would tell me how horrible things are at the house and how they no longer talk and a multitude of things relating how bad it was. He and i made plans to move in together in the next few months and get finances in order for the divorce. HOWEVER, just two days ago on his myspace i seen a note his wife left saying how they had a wonderful time at the mall and how much she loved him. I am confused, my gut says he's lying and i should just leave, but my heart wants to believe him and think his wife is just doing it to make me jealous. But i'm not really sure.
