I'm going to lose my shit *mother in law*

My mom in law and my husband lost their house a few years back when we just started dating, eventually they had to go their separate ways...I was 17 when my mom allowed my boyfriend "at the time" to move in and he paid rent, mom in law however lived with her daughter at the time but since moved from place to place as she's not comfortable. Ofcause I understand home is never home anymore after you lose your home. Long story short she literally followed my husband and moved in with him my mom agreed that was 7 years ago!! Since then my mom passed and my husband and I decided to move out as we got married my dad agreed that she could stay on however, next thing you know she became problematic and my dad ended up kicking her out she then followed us into our new place where she would sleep over at random times but still go back to her sister or cousin etc...money became a problem and my husband and I moved back to my dad where guess what a few months in she's back to stay so we go in the same cycle year in and year out. She eventually moved out again haven't seen her since now this is the present moment

My dad too passed away not too long ago in august

It started with a visit to give condolences next thing you know she has her suit case and back in our place never asked i knew I should of said NO she made it seem like it was one night now I'm sick and tired of her following us everywhere!!

I have 2 kids I need help she keeps using that as an excuse I don't need help! In her defense she cleans really well she cooks, does our laundry without asking buys my kids things she even pays a small sum of the rent but I feel nasty because I don't want her money or help I want my space I don't need her help I need my space!! It bothers me so much that she is living here to a point where I'm now living in my room with my kids and husband

I feel it's wrong that she stays even though my husband says "we have an extra room" why not? Why should she move from "family to family" my sister in law says she knows she's overwhelming and that's why her husband dosnt accept her there and sorry but I can do with some help with the kids!!(NO I DONT)

My mother in law and I we have been in so much heated arguments to a point where she told ME TO MOVE OUT and complains about my underwear etc I'm 24 years old cmon now! I never asked her to do anything but she comes back with money and food in desperation making sure we cannot kick her out

I'm tired of feeling like my husband's sister this is drawing a wedge between us too cause I'm always moody when she's around

I feel pity for this woman but I can't anymore

Am i so wrong 😔 ?
