I'm going to answer honestly - I'm only jealous when I'm not allowed to go!
I'm sorry that it hurts your feelings dear and I understand why! Your concern is "what if he sees someone prettier than me and decides he doesn't want to be with me anymore." Honestly, this is pretty much a pipe dream. Friends who worked in strip clubs don't want to date their "punters", they're too busy actually working!
Your self confidence is something you need to work on. You don't have to be okay with him going to Hooters, but make sure that you express that in an adult way and try and explain why you don't like it. Don't strop and make a fight out of it and scream at him. There is nothing more likely to push him into doing it more.
Remember, your partner's with you for a reason - he WANTS to be with you. As Alisha4u says, it's you he comes home to.
