Sasa,
Of course it hurts, and it's hard to let go of a 10 year long relationship.
But, you are sober now, your head is clearing and you are seeing things as they really are. You deserve better, much better, than this guy. Remember that early sobriety is a time for lots of changes, and you're going through one right now. Find strength in knowing that you are doing the right thing by taking care of yourself.
