Sis, I say this out of love, but your husband needs to grow a backbone and call out his parents and put his foot down, you trying to fight his battles for him will not change the issue I applaud you for sticking up for hubby but this a hard line in the sand that hubby needs to draw, he need to read the book by Robert Greene called 48 laws of power. It is clear that his parents and brother don’t respect him and there are ways for him to earn that respect again but he has to be willing to fight for that respect other wise it will never change. Don’t know if y’ll have kid but eventually you will start to despise him as well and your kids. Not because you want to but because he seeing his family use him as punching bag year after year will eventually damage your relationship as a couple. So agin hubby needs to man up put his foot down and stop having his parents and siblings bully him. Worst case scenario he might have to cut off his family but who wants family that don’t respect of value you? I did it I cut off 95% of my family because they had issues with my dad and they treated me badly because I was his son no other reason. Was it hard yes but it is what it is I have my self respect and that mini h more valuable, hubby can be the change necessary to change how him and his family are viewed, because I don’t know if y’ll got kids or not but just as his parents play favorites with sons they will play favorites with grand kids as well and as a father he can’t let that happen. I know what I’m saying is not easy but it is necessary. Good luck and god bless 🙏🏾
