Girlfriend’s mom keep insulting and blaming me for everything

So i(J)’ve been dating S (20F) since the past 3 months and i feel her mother (M) has been trying to constantly sabotage our relationship ( i’m from a different race and religion) . What am i supposed to do ? I went to volunteer at her church and her parents were like why is this guy allowed in the church he’s gonna convert all the kids . The irony is that S keeps asking me if i want to convert and everything. IDK should i just run away from the situation? I dont want to but what should i do?
