I was reading threw all this and the one thing that " Trigger " me was your fiancé abuses you ?
You said he doesn't want to get help , right ?

You are dealing with a loaded gun
What happens if your fiancé doesn't get enough sleep and the baby is crying nonstop what do you think will happen .
You said he has anger and stress issues .
He will snap !

I don't understand why put you and a baby right in danger ?
