Am I horrible?

I’ve been with my boyfriend now fiancé for 5 years and we had got into a really big fight and he said we weren’t broken up but I told him and everyone else we were, we were like that for about a month and I went around and slept with 5 different guys and of course had of course had sex with them multiple times! But we’re good now and engaged and I cut all those guys off..? Am I a horrible person for doing that?
