So a bit of backstory I've (25M) always been close with my aunt who is my mom's sister. My aunt has always been the cool one and the same with her husband. They both are really cool and love to drink/party, which is fine and during family get together's i'm always hanging out with them having a drink and even doing shots with my uncle. 

Now for the past 8 months to a year my aunt has been dropping hints that they want to go clubbing with me and another cousin of mine. I was actually kind of suckered into it and GUYS IT'S SUPER AWKWARD. 

Fast forward to now, i've been avoiding the "hey lets hang out at a bar or club again" conversation because i really just don't want to. I find it really awkward to party with my aunt and uncle outside of family events and I've mentioned this to my aunt before which made her really upset. So am I the asshole here ?
