Hello Frozen.
Welcome to the recovery forum.
Lot's of people break relationship and other social rules as a result of using alcohol. The trouble is, unless and until the alcohol is out of the way, there's not much way to determine what's causing what. I hope you will consider going to alanon, or at least getting some of the literature. There's also a list of books that some of our members have found helpful in the "power posts" section of this forum. It's titled "book club".
You'll find a lot of support on these boards and in the rooms of alanon. Whether you decide to stay in the relationship or not, it's good to communicate with people who have been through, or are going through the same things.
Keep posting!
Hugs,
Smoke
