You know its very sad things like this. We live in a fallen world no doubt but everything can be healed eventually, and I know and believe you will too. You sound like an awesome girl who deserves the best. Though it may be long, can you please take time to read this all?
Not sure if you believe in a God or not but I want you to know this: There is a God out there (97% of the world's 7.2 billion people believe in some sort of God, only 3% are atheist). The question then becomes which God is real? The answer is actually very easy: It's the God who created you and loves you. How then can I know which God loves me? Only one God makes this claim. Every other God (Buddha, Allah, Hindu Gods, etc) makes you do works in order to achieve and gain his love. Jesus Christ says I will love you unconditionally and I will die for you (John 3:16). This God gives commands to every family in the world, which if we obeyed, we would be living in a perfect world. What then are the commands?
"Wives, submit yourselves to your own husbands as you do to the Lord. For the husband is the head of the wife as Christ is the head of the church, his body, of which he is the Savior" Ephesians 5:22
It sounds to me from what you wrote you are actually trying to do this to the best of your ability. Wives must submit to their husbands. This is actually seen not just in Christianity, but also in Islam, and Hinduism (these 3 religions make up almost 75% of the world population). What command does God give husbands then? In Islam (the 2nd largest religion in the world), husbands are given permission to kick their wives out of the bedroom and beat them if they do not submit (Surat An-Nisā 4:34). Women have it easy in the Bible as it only says two sentences. Not so for men.
"Husbands, love your wives, just as Christ loved the church and gave himself up for her to make her holy, cleansing her by the washing with water through the word, and to present her to himself as a radiant church, without stain or wrinkle or any other blemish, but holy and blameless. In this same way, husbands ought to love their wives as their own bodies. He who loves his wife loves himself. After all, no one ever hated their own body, but they feed and care for their body, just as Christ does the church— for we are members of his body. “For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh.”
I hope you can change your husband to be that kind of man. If not, pray for him to become one. If your husband has an encounter with Jesus Christ, he will be changed and your marriage will be salvaged.
If you have any questions, don't hesitate to ask. I really hope to see a bright, intelligent woman like yourself get the best you can get.
