Boyfriend cheated what should I do?

Effie

I was going through my boyfriends phone and I found a screenshot of a snap that was sent to him. It was another girl’s boobs and that’s my biggest insecurity bc I don’t have the biggest boobs. I confronted him about it and obviously I caught him off guard. I really love him and I don’t want the relationship to end but I blocked him on Instagram and snapchat and when I unblocked him this morning, our date of our relationship was off of his bio. And that kinda hurt too! Well it hurt a lot. What do I do now? I don’t want to make it easy for him to come back. I want him to really know he fucked up.
