Advice please

So we have been living with my in laws for almost 5 months and it has been nothing but problems, my mil keeps making comments on the way I parent, the way I do things. She’s super nice but it’s gotten to the point where we have gotten in arguments because I don’t do things the way she would like me to. My brother in laws are involved in all the arguments as well. It’s a lot. I’ve been staying at my moms for a months since she’s leaving back to her country for good to be with my sister so lord knows when I’ll see her, and she’s throwing a tantrum on me spending time with her. My husband has been upset with her but he always ends up telling me it’s best to suck it up and let her win on these disagreements so we can all be at peace and continue llving there there so we can save up and get our house. I just don’t feel good about any of it, I want to move in with my step dad but he’s rejecting the idea bc he drinks a lot. I don’t know if I should just suck it up or get an apartment even if it’ll delay our plans. We are still very young we are 23 and honestly we have a good amount of money saved up for a down payment on a house but it’ll be to the point where we would be living paycheck to paycheck and we don’t want to do that. Im just drained and need genuine advice on everything.
