i dont know what to do! :(

Last night I was talking to my boyfriend of almost a year and we were having a heart to heart conversation I was very honest to him about my past before we even started  going out, and yesterday he told me everything he had done but I felt really hurt and sad as I had only found out pretty much a year later , I feel like I'm having somebody's leftovers he doesn't feel mine anymore, I guess I'm more hurt than anything.
