In a argument with my husbands mother

Okay so yesterday i was sitting downstairs with the baby until my husband came home from work around 9:00am so we are all in the kitchen grabbing some food until his dam mom said that we both dont do anything around the house ( we all live together) so i got pissed real quick because me and my husband has been paying and buying everything in the house for his parents and his whore of a step sister. His step sister dont spend a dime in this house we have been doing this over 3 years now .So today his mom askes me why am i ignoring her so i said back to her because what you said that we don't help witch is a lie because we clean cook and pay bills and get things you need for the house you hightly dont apretiate Me and my husband. Then she takes it to a hole another level she was having a bitchy attatude towards me and her son witch is my husband stood up for me and told her to leave me alone. As of today we are looking for place and i can not wait to leave this hell hole anyways his mother is still mad at us and dosnt say hi to her granddaughter whitch is fucked up.
