My husband cheated on me and now he wants us to become swingers. Should I do it?

Two months after we were married my husband cheated on me with his ex. He said he did it because I was constantly accusing him of being with her. Two after the infidelity he has asked me to join a swingers club with him. I not 100% over the cheating but we have a good marriage and I want to make him happy.
