My husband, whom I deeply love and cherish, has been distant for months.  He's expressed a shift and things being "weird'.  His job put him in a place where he was on the road and alone as we were living apart (not intentionally, just circumstance).  After claiming he needed time and space, he finally opened up to me.  He told me that he has been questioning his sexuality and has had male encounters before our marriage.  He was apologetic, crying, sad, all the emotions.  This happened  4 days ago.  He is currently traveling for work so I am not physically with him.  
I have been processing this shattering news and trying to make sense of it.  I get tidbits of information from him, mostly about the affair.  I don't yet feel anger, but just deep sadness and stress everywhere.  I am with our two boys and trying to remain "normal".  
After speaking to him today, I asked if the affair would be continuing and he said without any hesitation, yes.  definitely.  no question.  There was no consideration for my feelings.  
He has expressed his desire to work on our marriage and that hopefully we can get through this.  I'm not sure how honest he is being and feel that the truth is gradually coming out.  
I'm sick over this whole thing and question whether I can tolerate another person in our relationship.  He claims it is not serious and just fun right now.  
I can't imagine being with someone else let alone betraying him the way he has betrayed me.    I had sympathy for him but after the last conversation, I'm not sure what I feel.  I'm truly in shock.  
I am seeing a therapist.  He is actively searching for one.  
I am stuck and lost and so many feelings.
