How do I get my ex-boyfriend back?

This isn’t just a typical break-up situation well me and my boyfriend had only went out for about 2 weeks, but instantly we relised how good we were for eachother…we could talk, laugh, party, be honest, play video games and watch movies all night long so everything was great! We wanted a family (yes I know it seems so soon) but we were so close! And my parents loved him, so did the rest of my family! We had unprotected sex all the time so at the moment I might be pregnant but it’s to soon to tell. One night he just broke up with me telling me he wasn’t feeling it anymore. A couple days later, I asked him if he broke up with me becuase I did something wrong and he said “no you were great, I just wasn’t feeling it anymore becuase I’m going through so much sh*t right now and I don’t want to bring anyone along for the ride” I understand what he ment becuase he has to go to court again on june 2nd and he isn’t sure if he is going to jail. When we first started going out he told me his situation and I told him I would wait for him and that I wanted to be with him…he knew I had never felt the way I felt for him with anyone else. What can I say to him to have him understand that I want to be with him and be there for him? Or is he just using what he said as an excuse to leave me, even though he know’s I might be pregnant? My grandmother passed away just a couple days before he broke up with me aswell, and my best friend left and is always mad at me. I lost so much! But I can’t stand losing him becuase he was kind, gentle, sweet, strong, honest, open minded, and so much more! Please answer
