Should I stay or should I go?

Evelyn
I have known my boyfriend for 7 years. We been off and on. Now that we are fully mature we love each other and wish to stay together. My mom had a talked with me and told me that she doesn't agree with me talking to him. She's always bringing up the past saying that what he did was wrong. Well what he did was talk really bad about me in the past but that happened because I was talking to some other guy. I know it was wrong what I did. But I was Young and stupid. I always say that people change and we do. My mother doesn't agree with me. What should I do ladies? My mom doesn't know I'm with him she thinks we are dating. I can't hide it no more.
