Hello
Yes, the behaviour is normal for an addict! Sad, but true. I remember all kinds of discoveries when my son was an addict! All involving sex!! I remember thinking he was gay, oversexed, sick! I, like you, couldn't turn to anyone for help or advice, mostly because I was so embarrassed. That's when I found this site!
I do want to say one thing, not to scare you, but to give you a head's up, you need to take care of you and your baby!
Does he work? Are you frightened for your safety?
In any event, do try Alanon. You must take care of yourself and child! This is not the man you married. The only way to help him is to let him find his own way! You cannot help him, only he can do that!
Hugs, Devastated
