Jess,
I think your situation warrants some advice from a professional, not a bunch of well-meaning forum posters!
Something to remember as well, YOU have to take action to cause change. We cannot do it for you. Your situation is a dire one indeed and there is room for improvement.
As the old addage goes “poop or get off the pot.” But remember,
both of you need to be willing to fix it. If you both aren’t on board, you’re just going to be spinning your wheels. I know the Church teaches that married couples cannot simply “divorce,” however I know our loving God the Father does not want anyone of His children to be miserable either.
Get help. From the Church. From a therapist. Ultimately a pro.
We have a bunch of wonderful and caring people here who seem to be genuinely concerned and want to sincerely help you, thank the Lord!

When it comes down to it though, this is only an internet forum.
That’s just my $.02. Take it or leave it.
Peace and God bless.
