This is out of context. Do you guys often go out to bars and clubs? Is your husband generally prone to the "lust of flesh"? What is your agreement regarding going to bars and drinking? What is your agreement regarding dancing with other people? For my husband, dancing is a form of torture, he will not dance under any circumstances; so on a rare occasion that I happen to dance, I will dance with other people; it has nothing to do with lust, it has everything to do with me liking to dance. You should know your husband by now; if he's a lustful person, it will manifest itself in ways other than asking some girl to dance. Generally, if something bothers you, bring it up in a non-confrontational way and discuss it with him. You need to communicate your expectations. It may be that to him it's simply not a big deal and he has no idea your whole world is about to collapse just because he was in the mood to dance with some random girl.
