What can I do to help my boyfriend forget about his past?

So, me and my boyfriend are 14 year-old high-schoolers that were best friends when we met and slowly started to like each other, it has officially been ten weeks and we started dating on the sixth week of school. The more and more as school goes on, the more and more I slowly find out about him. So, when his mom got pregnant with him, she tried to abort him, luckily, it didn’t work, and as soon as he was born, his dad left. Since then, his mom got married (his mom and dad were never married, they just hooked up) and she had three more children. Through the years, it hasn’t gotten any better. They used to live in a house, then in an apartment complex, and now a trailer. His mom works three jobs, and my boyfriend works a job on weekends. He curses all the time, but he was brought up that way. He and his siblings never get any new clothes, and his clothes have rips, holes and tears all up and down them and he always wears the same pair of shoes. He hardly ever does his homework, but he doesn’t have time because he has to constantly watch on his siblings when his mom is working, and works on weekends. He’s colorblind, an ambidexterity (both handed) and is deaf in one ear. He also has a really bad temper and hair to his shoulders. People constantly pick on him because his life is so ‘different.’ He grew his hair out so that he would be ‘different’ in other ways. He sings out loud without realizing it and plays on his phone, its the only way he gets away from it all. I don’t know how to help him or what else he’s hiding, whenever he tells me more about his life it gets worse and worse, every time I think that that’s as bad as it gets, it gets worse. His mom and dad both told him that he was a mistake, and the only two people in the whole world that cared about him died a week apart. I don’t know what to do, I wish I could do more, but what else is there to do after all that happened? Also, his birthday is coming up and I want to make it the best day of life, so, my question is, how do I help him and is there anything birthday gift that could possibly help make this any little bit better? Please, I’m desperate, I don’t want him to do anything that he’ll regret, please. Is there anyway that I can make his life better?
