I'm sorry this is happening at this time in your life.
Although different circumstances, your post reminded me of a very difficult time in my past.
My ex was in love with another when I was pregnant with my youngest son. I endured unimaginable months, in the hops that he would "wise-up" and put his family first.
I was in it for the long haul, regardless of how he had hurt me.
When I had my son he was barely there, more interested in talking to "her" on the phone while I endured labor and delivery. He calmly left when he knew we were OK. He barely spoke to me the entire time...I was a burden I guess.
It was THEN, that I knew that I deserved more, and that he was not there for me when any human being would have known they should be. It was then that I knew I was ending our marriage.
You have a lot on your plate, and need to concentrate on your health. As much as it hurts, I do now believe in "signs" that something has to change.
His behavior may be your sign.
I wish you the best and will keep you in my prayers
