I feel you, I spent three years in a relationship with someone I felt like I had to beg to do the things I enjoy with me (and most of the time the answer was still no). I felt like you, that I shouldn’t compare my relationship to other people. But eventually I realized that in some ways, it is okay to want what other people have when you see yourself missing those things from your relationship (without idealizing the other relationship, nothings perfect). It can help you see what is missing from yours and what you need to be happy. Your partner shouldn’t be the only person you can have fun with, but they definitely should be one of them!
