Who would wait for a loved one if they got incarcerated?

I have a boyfriend let's call him j, he's such an amazing person...who's made a mistake. Nothing big but he's paying for it away from me. It's hard trust me, some days are easier than others if I don't think about him being way I can get through the day. But for example when I receive a letter from him the day after I'm in a depression again. Just because I want him to come home so badly I just have to wait a little bit longer each day so that I can see his face again
