We been staying with my mother in law for over a month because my husband's brother is fixing his car but he has been bullshitting us saying it needs different stuff for it. Today we thought the car was ready and he calls to say it needs something else!!! Now my freaking husband is talking about wanting to actually move in with his momma until we get on feet!!! I don't wanna even live with my own momma!!! Why would I live with someone else's mom???!! I'm not too happy about this cause I love my privacy and living in my own space!!! I am already a bit stress out from other stuff and now this??
