Living with boyfriend and family but mum doesn’t like me

I am currently living with my boyfriend in his parents house until we have enough money to buy a house. I find her very intimidated as it is and my anxiety is making things 100% worse. she doesn’t like me because I don’t interact with her etc. But I try my hardest but I’m just so anxious to start a conversation and she doesn’t really start ones either as she just groans at answers etc. Anyone been through this living with parents/parent that doesn’t like you
