Cheating..

Me and my bf had a really bad falling off where our communication was bad and our insecurities got the both of us. Basically, there were other guys texting my phone and at one point i wasnt even sure if i felt the same way for him anymore. But as time went on, i stopped texting the other guys and focused on my bf. However, just recently we had a horrible argument where our true colors came out and he admitted to me that he had sex w another female bc he thought that I had sex with someone else .. We stopped talking for a few days and then eventually spoke and decided that we still wanted to stay together and put it in the past. We talked about where we went wrong in our relationship and how we want to prevent it from happening again. I feel like we are stronger than ever, but i just dont want to be made of fool of by my peers for taking him back. Am I stupid for taking him back?
