Help :/

My now ex has gone through a lot all his life like its bad. Hes always had to handle everything on his own. he tends to shut people out, also out of fear of hurting them, he doesnt always handle his stress and anxiety and can get really overwhelmed and cant always help himself. And he doesnt have the best home life. Well like 3 weeks before we broke up he had been really busy like going out of town, catching up on school, having a lot to do around the house. We had a conversation about it bc I was overthinking and he explained and we were fine until one day I was having a bad day at work and took it out on him for being busy when I wasnt upset with him and I shouldnt have. I apologized the next morning but he needed space. Anyways last Monday he came over and he was bawling his eyes out like Ive genuinely never seen him or anyone cry so much to the point where they were shaking, could barley speak, gripping his steering wheel until his knuckles were white and my head so tight. He said he didnt want to hurt me by having so much going on. He just kept apologizing and he said he loved me and wants a future with me when I asked. I asked if we could just take a break, he said the best he could say right now is that hed think about it. I don't want to lose him
