Re: Can jealousy cause someone to cheat?
People have affairs for many reasons, none of which really justify the action itself. There is no excuse for cheating. Whatever is going on, if you are so unhappy in your relationship that you feel the need to be with someone else, then you should end the relationship so that you are free to be with someone else.
I do know that jealousy can cause a lot of problems. If one partner is constantly jealous and accusing their partner of cheating, the accused partner may eventually get fed up and actually cheat, because they feel "well, if I'm going to be accused and punished for it, I might as well actually do it". Does that make it right? Of course not. So, she might say "Well, I was afraid you would cheat with them, so I beat you to it", but that doesn't make it any more right.
I will say, though, that I would be bothered by female friends calling my boyfriend hun, babe, or something along those lines, and it would cause problems for us if he knew that and didn't make an effort to make them stop. However, I wouldn't cheat. I would simply sit down with him and say, "Honey, I don't mind you have female friends. But I do mind them using terms like hun, babe, etc., that I feel are only appropriate for us to use for each other. This makes me uncomfortable, please make them stop." At that point, I would expect him to go to them, and tell them, "You calling me X is making my girlfriend and I uncomfortable. Please stop or we won't be able to talk anymore." If he didn't, I would feel that he doesn't place much importance on our relationship and that would make me wonder. So I do think, in the future, you may want to be proactive and put a stop to things like that.
