What is going on?

I have just split with my bf of 7 years.  Since last August he has had 2 episodes of going AWOL from the house.  Was on antidepresants and seeing a psychiatrist (one appointment).  He left 9 weeks now.  In that time he has said he does not miss me, then he does.  The latest thing is that the psychiatrist told him to leave me, despite there being no abuse.  He has wanted out of the relationship for a long time apparently.  He says he does not have depression anymore.  Have seen our gp who feels that there is no way he would have been told to leave and she never saw anything wrong.  Dont know what to do now.  Has anyone any advice??
