Would it be stupid to stay with someone you love that has cheated on you? My SO and I have been together for almost a year. We've had trust issues from the start mostly because we have both cheated in past relationships. He thinks that I've cheated on him, but I haven't. I'm very much in love with him and I don't want to be with anyone else. Because he thinks I've cheated on him, he slept with someone else. He claims that he loves me but did it because he "knows" that I've been doing the same. I don't think that this justifies his actions at all. I love him very much and he is so important to me, but I'm starting to think that maybe it's time to walk away. Any serious advice or suggestions?
