Divorce

8 months pregnant and going into the process of divorce.  Since the beginning of the pregnancy he found the ideal woman and he's been involved with her all the pregnancy time.  We've been married for 10 years.  8 years trying to conceive and when that finally happened, he decided to be with another woman, although attending therapy to see if we could recover from infidelity. He never left her.  He blames me.  I'm expecting twins and this is the worst time ever.  Help me please with some words and advice.  I love him.  He doesn't love me anymore.
