g/f cheated, I love her, she loves me.now girls want me should I do something on the side?

ok… in the beginning of our relationship my g/f cheated on me… she did it because I didnt want to give her sex… this was because i wanted to see if she could last atleast a couple of months without cheating on me… and she didn’t last… I found out that she cheated on me about 10 months later when we had actualy fallen in love and everything was like set… I can’t help it but I can’t stop thinking about what she did… she cheated and in a bad way too…like she told me she was going to her cousin’s and made me drive her and pick her up from the apartment… (yea she pimped me )… but now… i have the opportunity to sleep with sooo many women… i have a couple of girls who want to threesome… and another who just wants to keep a regular booty call partner… and lastly i have her best friend who actually did stuff with me in the past and now wants some more… I have actually been doing jelqing exercises.. sorry off topic… so yea what should i do??? should I cheat?
