Emotional Support

Hello my boyfriend and I have been going out for ten month and in between those months he broke up with me for almost two months since he had a lot of personal problems at home and emotionally couldn't have a relationship . That devasted me completely and I would go to sleep crying since he was my best friend and felt I lost a family member . In that time I was with friends the whole time and made it seem like I was better without him but I wasn't . About two months ago we got back together after he begged me to be with and promised to never let me go again . It was great to be with him and all but sometimes I would think about what happen that day he broke up with and start to bawl my eyes out . How come I still cry my eyes out thinking about what happened when I'm very happy with my boyfriend like he's a better boyfriend from when we first start going out . Should I tell him about this or keep it to myself
