SEX WITH OTHER WOMEN

going out for 4 years my boyfriend and i were on a break he had sex with other people because he had his needs.

he used it as an excuse because i was not there to give it to him he decided to get it from several others including 7 of his coworkers and unknowns.

it hurts knowing he would do some shit like that, especially after telling me how he still loved me and he was going to be completely honest with me even if it meant he would lose me.

i need ideas of what the fuck to do.

i love him but i do not think i will be able to make peace with this one.
