Such a boyfriend might as well get rid of him and break up quickly. Because such people have quality problems, a leopard cannot change his spots. Even if you quarrel with him or take other measures, he will definitely stop doing so, but he will continue behind your back. Today he won't have an affair with this woman, and tomorrow he will have an affair with another woman. Don't believe his promise, I'd rather believe in ghosts than men's broken mouths!
