What attracted you to him in the first place?
Going by your other threads, I think you likely aren't giving it a real chance if you are on forums and going to clubs looking for other men.
Sure, go out, meet new people, but don't flirt, don't go out simply to find men, regardless what you do with them.
Do you have friends of the female gender?
Have you discussed things with your husband in a cicilized, mature manner?
