how do i make my mother in law. like me

so she never liked me because i used to drink at her house and get drunk , and don’t say hi sometimes when she’s watching tv. i been with my boyfriend for 3 years. i haven’t seeen her for about a year now or more because she told my boyfriend to not let me go over anymore . i did nothing to her . and his sisters don’t like me now . i feel sad. she speaks full spanish and i don’t speak it very good i just know basics.. i understand spanish tho when they are talking. mind you im 24 and he’s 27
