Looking for any inspirational stories fit those that have been cheated on but came out of it with a stronger relationship. Can he really change and go back to the man I married?

We have been married 5 years and have 2 young girls. He said they were just hook ups but I am having a really hard time trusting him. I want our relationship to work. I don’t want to get divorced and break up our family. I don’t know what to do, please help!
