First-Did you take the fellowship at Harvard? That sounds like such an awesome opportunity for your daughter and yourself.
It does appear your M is in MLC......but I always wonder about him being previously married. Much like cheating...I think that divorce could be easier after the first one and that line is crossed. It could actually be he was in MLC during the initial marriage, was still in it basically when he married you, and continues to be in it. There is talk on psyche boards about certain people never actually getting out of the MLC tunnel.....your previous posts really make me wonder about that.
My advice would be to totally focus on you and your daughter....if he comes back so be it. Reclaim your life and show your daughter how a proud and strong woman can live and prosper.
