Normal that your spouse compares the relationship that we have with the relationship that he has with his mom?

my husband and i been arguing because we live in a one bedroom apartment that was working great for us until his mom came to live with us. when we new she was going to live with us we talk and agreed that we needed a bigger place . we was going to move months before her arrival but we never did .now she is living with us for 5 months already and i feel really uncomfortable i lost my privacy. shes been moving everything around. my husband spends days without talking to me. if he has any problems i always find out from another person but not from him. i keep telling him that we need to move but he keeps telling me that he needs more time. he is on the process of bringing his 16 year old brother and sister from his country and like his mom hasn't found a job he has to help her support them. after i came from work i start talking to him and i asked how much time is it that he needs so we can move. also i i felt that he is changing his attitude towards me.that we wasn't having any communicating at all that we were not even going out and spending time with each other.day he tells me that he fells that i am pressuring him that i don't help him and it will be better for us to take time apart that he was going to move alone with his mom.he tells me "that his mom treats him better than I and that she doesn't ask him for anything like i do ". he also said that she doesn't complain that there is no room that she is fine sleeping on the air bed in the living room not like me that i should be more like her, finally that his main concern is his family.i told him that she doesn't complain because this is not her house and because we are supporting her . then 15 p by and he acts and talks to me like nothing happened its that normal?????
