Advice needed

I've been in a relationship for 13 years now. Honestly it shouldn't of been that long. Majority of it, about 10ish years of it, has been filled with cheating, selling drugs, using drugs and jail. Through all of it i remained loyal to him. He proposed years ago and we have one child together. For about the last 6 months he has been home, remained clean, taking classes, and getting his life on track. However, I am now beginning to feel mentally checked out of the relationship. I find it hard to trust him and I keep thinking about all the things he has done the past 10 years. Now I am unsure if I should end it or move on. What if I am making the wrong choice for my family? I do still love him very much and he is finally doing what I stayed around for but Im not happy and I don't know if it's just a phase. I started feeling like this in December and the feeling is still there. A little background on myself, I am attractive and successful, have always been the bread winner and was never into the lifestyle he was living. I have always been fine on my own but Ive recently realized I don't want to be that "strong, independent woman" anymore. Help!!
