Barriers

My bf and I have only been together a year. My mom doesn't know we're together because he's Muslim. She forbade me to even talk to him but that was after we started dating. I told him and he was like his dad said the same thing. But we're too stubborn to realise we can't be together. He always tells me he promises that we'll be together no matter what. I love him with my whole heart. What do I do??
