Boyfriends mom

Erin • Life isn`t about waiting for the storm to pass it`s about learning to dance in the rain.
So I'm 17 and so is my boyfriend. We have been together since we were 15. He is the love of my life. When we first got together I loved his mom and we got along together great! But a year ago she started dating this new guy. Ever since then she has hated me and we constantly fight over him. She always controls him and doesnt let him hang out with me very often. What should I do?
