Your mother is an enabler. Some women confuse submission with weakness. How would she watch your father emotionally,verbally and physically abuse her children and keep quiet?
That's why the way you enter a marriage matters a lot. If you are someone with no values and morals, you would end up tolerating anything.
Some men think they need weak and quiet women but actually they don't. There are men you have to use absolute madness to follow for them to calm down. There are men you have to use diplomacy to follow and get what you want. There are men, you have to be absolutely quiet to get what you want. That's why I do not believe in all these seminars where they advise women to be gentle with every man.
I would advise you to leave that house and stay on your own. You are an adult. Stay away from that toxicity. You can send money home but avoid coming back often. Dont do anything to your father. It's left for your mother to correct him and if she doesn't, it's not your business anymore. As for suitors, Just pray to God, the one for you will stay.
