Idk what the hell to do

I'm in a relationship I've been in for a year and recently I found out my boyfriend cheated and I gave him another chance but nothing seems the same way, I have feelings for another person but I love my boyfriend. Idk what the hell to do anymore. We broke up for 2 days and I got back with him. During the two days we broke uo, I started falling for another guy. I don't know what the hell to do anymore.
