My boyfriend was found to be having an affair with another woman, but he firmly denied it. What should I do?

If you don't admit that this is right, he doesn't want to have a bad relationship with you. He's missing you, too. Nowadays, young people have never had enough fun at one time, but you are lucky to have had a serious relationship before the accident. Others, you're welcome. Since it's a text message, don't deliberately ask who sent it to whom and speak ill of me. The key is to warn him that it won't happen again. I can forgive you this time, but not next time. Don't frighten him too much. If it's hard, you can be softer. For example, ask him if he still loves you, then ask him if he likes other women and so on. Don't contradict, just try to solve it.
