Welcome to SR!
Sorry about what brings you here...you might want to read the stickies at the top of this forum.
I don't know how to answer you....just honesty...I am worried, I don't trust you anymore, I don't feel our daughter is safe etc.
If he does have alcoholism...this talk isn't going to fix anything probably but you will at least be able to address it...which in a marriage you have every right to.
You have the right to be heard and if it is a problem for you, then it's a problem.
