He's 28 and I'm 25. He won't tell his family about me. what do i do?

My ex boyfriend and I have been talking again to each other for the past 5 months we known each other for 7 yrs we were togther for 5. We havee had sex and our relationship with each other is great. We communicate like never before. We love each other. But we can't have a "normal" relationship because he is hiding me from his family. He doesn't want to tell his family he is talking/ seeing me again. His family means a lot to him he doesn't want conflict with them. His mother doesn't have the best impression of me because in the past when we were together we did have problems in our relationship (immaturity). What do I do??? I am willing to stick by this man through thick and thin. I love him but I want to make things work and be able to go out and not hide and ONLY see him weekend nights when his family is not visiting him. He works with his dad. Lives with his brother. helps his sister with her kids in the day on weekend. He is always with them.
