Is it about personal growth?
Sometimes you just feel that you haven’t experienced or accomplished everything you’ve wanted to, and you fear your relationship has gotten in the way. But you tend to set the precedent for your own relationship. So if you haven’t been traveling together enough, going out enough, going after your dreams enough, it might be because you simply believed it was something you couldn’t do with a partner, so you never tried. But, you don’t necessarily have to give up your relationship to experience life. Your partner may surprise you if you simply tell him, “I want to do more of x, y or z.” Also, if you’re going to spend your life with someone, it should be somebody that you can go on adventures with and grow together with, because people never stop growing. So, you may as well start trying with the person you’re with now.
