Ex boyfriend

Ok so I dated my boyfriend for three years he cheated once but it lasted for around 2 months my stupid self forgave him and we went back to be together but i didn’t really give myself time to heal or anything so when we got back together I would always fight about it even if he gave me his phone I would always tell him that it wasn’t the same now we broke up one month ago. I told him that I regretted what I said and that I would stop bringing the past up and he said that he wanted more time. he used to talk to the girl on Snapchat so his score would go up now that we are on a break his snapchat score is going up again and it hurts me cuz I think the worse and I don’t know what to do about it. Because to be honest i been begging him but he say he doesn’t want to go back yet..so idk what to do because even if I tried to talk to someone else is just not the same:(. And it hurts so bad he has been my first love we been together for a long time now..
