My parents don't like my bf?

yeah i have a simular problem my mom doesn't like my bf but in the begining she was like yall need to hurry up and get married now her and my step dad are making up lies to break us up. pretty much she chose my step father over me and i am still with my bf and now we are engaged. i havent talked to my mom in about 2months. but i hate it i just wish we could all get along but u have to be independent and learn from ur own mistakes they will regret it when they realize how much they have missed out of ur life so i wish u the best.
