I agree with Starr. I'm sorry, and I know other people have differing opinions, but when I met and started dating my spouse, we didn't get married to go out to bars drinking and dancing. We were glad to be done with that life. And in fact, had mostly left it behind already by the time we were dating. We didn't go out to bars on dates. Or dance clubs. We went to dinner, and movies, and destinations and did activities together (canoeing, hiking, went to sporting events and concerts). All things that we STILL go do together or with our kids.
I don't understand why married couples are attracted to that scene at all. Some are, I guess. Just not us. But to go without your spouse...there is an underlying message that you are looking for something if you are there. Whether you realize it or are willing to admit it, or not.
No, you don't need permission to go, but have you asked him what about it he thinks is inappropriate for you to be doing? Go have dinner with your friend. At a restaurant even. Go see a movie with her that husband has no interest in (a chick flick or something). Go take a bottle of wine to her house and sit and catch up. Or invite her to your house.
But partying at a club?? I don't get why that would be something you'd be interested in. I really don't. You like to dance? So dance with your husband. Turn up the music and there you go. Or is it that you prefer putting on a show for strangers? I just don't understand. If you and husband enjoyed it together, fine. But why you would want to go do that alone, without your spouse... that just seems like you are looking for trouble. It's an easy way to get caught up in an extramarital relationship. Booze, dancing, and no husband around...
