Terrified of losing everything I built

M36, married for 7years with 5yo kid. Im immigrant and brought my wife here, did everything right, worked hard, bought a house, have 401k, didn't cheat, took care of my wife and kid with autism

Despite all that I married an ungrateful wife who blamed me for everything wrong with her life. She has no accountability. The worse is she has a very foul mouth, used extremely hurtful and disrespectful language against me, she also said hurtful things to her side of family as well but like me they all tolerated her. She is so arrogant that she will never accept therapy, it had been completely on me to hold on this marriage the past 7 years, when I finally snap it will be ending certainly.

The problem is Im not tolerating all this because I am afraid of losing her, im mostly afraid of losing everything I worked so hard for. The house i bought with our name on in literally the down money is all mine and my saving working intern and eating panda express for years and years. She did nothing to contribute financially, we all eat doordash daily for meals.

I dont see how this will get better from here, just keep getting worse everyday.I feel so unfair as i did everything right, being a good dad and loyal all that time we had distant relationship when i studied abroad.
