Ashamed...?

Ladies I'm not sure how to feel. But here's a sum up of the situation. I've been in a relationship for about 2 years. He's great and I love and adore him. However he can be seen as a problematic person. I suppose I need to note that we are both 18. I've been with him since we were 16. At first my parents loved him and he was always around. Until his life unfolded before them. My SO was a drug dealer. Not heavy duty stuff just simple marijuana. He got caught and was sent away for a month. At the time he was 17 and was charged as a juvenile. While this had happened I kept it quiet from my parents. Valentines was around the corner howverr and he still wasnt out. Things began to grow suspicious for my parents. Finally over a family dinner I broke and told them. I had been holding it in for to long. They were supportive at first told me everything would be okay. Only because I was hurting so much knowing I couldn't contact him. His sister was harassing me on social media. Trying to prove he was cheating on me. It was a mess and I couldn't hold the tears. After time had gone by they began to grow distaste for him. While I waited for his release my mom kept asking me what will I do when he's out? She wanted me to leave him and move on. I just couldn't bring myself to do it. I may seem naive and even dumb. I can't defend what he has done. He's had a hard life growing up. And needed the money for his family. With no dad and a single working mom living off tips. She kept pestering her son for rent. At the age of 15. As I said problematic family. But I love him all the same. I believe in him. He's doing better now than ever. But still not good enough. The reason why I bring this up is because today my mom told me my older sister (21) has a boyfriend. Her first relationship was awful and she couldn't find anyone since. I was happy for my sister. Up until when my mom started bragging saying this new gentleman was a nurse, in medical school, and working at a hospital. Showing me his pictures and practically rubbing it in my face. I felt a bit sadden. I'm currently in medical school as well. For pharmacy. A trade school. Starting out young. My family thrives off success and my boyfriend is anything but that. They forbid him around the house. And now they are opening their doors to this new gentleman they'll rave over. While I'll just feel left out. I've always felt my relationship was portrayed as wrong to them. It makes me doubt my relationship when I don't want to leave him. I know this is a lot and I have lots more to say. What do you ladies think? No hate pls
