Yep, everything else about us was amazing, but her whole life hovered around me. It was ridiculous. She would bitch at me for making plans with my friends...."you're in such a rush to get out of here." Uhm, no, I'm making plans with the other important people in my life.

Of course as I said, otherwise we got along well. She was beautiful, funny, intelligent, and kind. I stayed with her because I did love her, but I simply wasn't consumed like she was. It ultimately was our undoing, and after spending nearly 6 years together, we split up just a month shy of me asking her to marry me. 6 years, and all the while I encouraged her to do the things she loved and to see her friends, but almost nothing. She would repeatedly talk about wanting to be a published writer, or write sitcoms, and she did next to nothing to pursue those goals. I on the other hand was working my ass off to become a journalist, which she also resented me for. While I had my own professional goals, a big part of that was working to build a life for us.

I of course had my had my parts in our breaking up, but when we got together, she was fresh out of college, and I, having been that person consumed with their partner, knew better than to abandon myself in a relationship. I was in the thick of discovering who I was and who I wanted to be, and she wanted to be with me. Not a good mix and something that I will never repeat.

TL;DR: Encourage your partner to seek fulfillment outside of your relationship. If she attempts to do so, then great. Help, support, and even participate in them with her, but this sort of thing is bad news through and through.
