Aaron,
Mind if I get real personal here?
My mother was an angry woman. We children felt sorry for dad; I endured a lot of unnecessary grief. It pains me to read of other people's happy childhoods - things parents did with the children for fun. This was not our story.
Still - I am the child and she the parent and scripture teaches us we are to honor or parents - it is not conditional (Hey! this is in the ten commandments!).
Dad died in 2007, four years ago at the age of 80. When he died I was glad for several reasons: one, that he will no longer have to endure mom's criticisms and another that he will not get old and get Alzheimers like some of his brothers did.
Anyhow....
Dad was faithful. We children look at him with an immense amount of respect - not just because he was a dad but because of what he endured, taking it graciously. He was not perfect, not by a long shot, but not many men could endure what he did. He accomplished it only by the mercy and grace of God.
For some time afterwards whenever mom would talk about dad she talked with a lot of venom and anger, about how dumb he was in financial matters, etc...(He left her a wealthy woman.) However, after a while I think she realized there is a LOT of work in running a farm and that it is stressful.
Today. Mom's attitude has changed completely - a total of 180 degrees. She talks nice about dad. She will say things like "I think dad would like that.." She compliments me, praises me - something I never dreamed would ever happen. I can actually do something right! WOW! She is nice! I like to be with her, not just because she is mom but because she is nice!
My point, Aaron, is that dad's faithfulness in face of tremendous difficulty is a wonderful testimony to the mercy and grace of God. And mom did change against all odds against that ever happening. Statistically, it just doesn't, not as old as she is.
Others said you need to pray and that is excellent advice. You said you feel like leaving - no doubt you do. But remember you made that vow to God and you are responsible to uphold that vow - only God can release you from it.
On the practical level look for ways to please her. When my mom had knee replacement surgery, I love to recall how dad would sit in front of her and wrap her leg. Mom loved it and dad loved doing this for her. This is a precious memory - there are very few and this is one of them and it gives me lots of pleasure.
There is no way in the world you can stay faithful to the LORD and her apart from a close walk with HIM. Just know that your LIFE is totally dependent on this closeness. Stay there...
BTW, do you any clue what is fueling her anger? Unconfessed sin will do that. Did she have an abortion? (Sounds like it to me.) Is she a victim of sexual, mental, physical abuse? Immorality at any level? Given the spiritually sensitive nature of a female, these memories will evoke anger unless these things have been laid at the foot of the cross and LEFT there. If she is a victim of abuse or had an abortion she will need counseling by a caring, loving person who can lead her to forgiveness and heal the pain inflicted upon her soul.
God bless. And will pray for you.
