How to deal with the temptation ... to fight? I don't know either, people.
Now back topic, I haven't been tempted to be with another man than my spouse as long as those relationships were ok.
When I got tempted then it was mostly for more reasons than one man being attractive.
I have learned to better stop relationships when it starts to be like I look at other men with "thoughts". Because that's my personal sign that something isn't right with the relationship I am in, otherwise I am not tempted.
