I don't think you are nuts. Maybe you can help yourself not "get over" (implies your opinion and feelings are "wrong" and that is never the case) but accept your boyfriend's opinions and feelings as being his and his being "allowed" to have them, as you are to have your own.

I don't know what your thinking is that you allow what other people you do not know are doing to affect how you feel about yourself. Why are your feelings hurt because of what other people unrelated to you and your life do? That sounds a bit controlling on your part, wanting the world to operate according to your rules or likes/dislikes and opinions of what is good or bad, right or wrong.

I think your boyfriend is insensitive in his stating "it" is more important to him that you are, but I can see that his getting jobs and money could be more important to him than your attempted control of his getting such jobs in venues you find immoral or obnoxious but which he and their patrons do not. Sex sells. We all know that. But it is not like you are being forced to either participate or even watch? Think of all the other strong concepts that can be either "good" or "bad" such as money, religion, politics, etc.

Were I you, I would substitute some other concept for "sex"/"burlesque". Think of it as dancing for money or making a living (which is primarily what the women are doing). Not everyone has someone to live with and help financially with taking care of their children. See if you can feel a little sorry for the actual women rather than impersonally about the dancing concept, most of which is created from your own thoughts and imagination rather than any actual basis of participator (both dancers and their watchers) thoughts and feelings at the time.

I often find it easier to be upset about a "concept" such as "burlesque dancing" than to be upset at an actual person I think about and their actual circumstances that make them like myself. It's a known psychological situation to think of why you may cut someone off in traffic, have a good circumstantial excuse (being late, dodging another "crazy" driver, etc.) but when someone we see does it, we immediately blame their personality, not their circumstances instead, thinking of them as mean or rude people when they may be rushing to the hospital with a sick child lying in the back seat for all we know.

So, see if you can stop thinking of "kinds of dancing at regular music venues" and think about the individuals who might be attending and hoping for relief from depression or a fun time with friends, or hoping your boyfriend makes a lot of money or something more "personal" like that?
