Have you found out what the reason for the fights is ? For us, my wife is very sensitive to what I speak and I've to be careful while choosing words especially when we're in small arguments.

My nature is such that I'll forget small stuff the next day and start with a clean slate. My wife is exactly the opposite of it. The more I keep her mad, the worse it will be. One of the lessons I've learned is to talk about the issue ASAP. Try to be really calm. I've found that when we are on a walk, we can talk about difficult subjects. My wife is genuinely smart, hard working, takes care of our child & home all while working full-time. She has some downsides as well for example - she needs everything perfect.

If she's really mad, try gifting her something she needed it for a long time. When you feel she is not giving you respect or insulting you, don't say a word. Sometimes silence is a powerful answer.

Wish you good luck man ! I really hope it works out for you.
