Not at all shinta. I, like you and Buff and Animeniax despise crab sticks for the same reasons in fact. There are plenty of things I hate on principle, food being the least. Speaking of food though, I hate rice. I really really despise rice, I am so tired of any and all things rice.
Anyway I just want to get at Buff. I was going to write a long detailed post about the issue but I am too tired to do so at the moment. If you are looking for an out in your relationship just get out, don't try to rationalize or justify it. Self improvement is fine and if you think someone else has better qualities that is fine too. Relationships don't work because people are soul mates or some crap. Good relationships work because both parties are committed to and continually work at improving not only their relationships but themselves. Any talk of settling sounds to me like you have some deeper issue with some aspect of your relationship and you should probably discuss that with the person you are with. As you stated the attributes you like about your partner are not unique to her. There will always be someone smarter, or more beautiful, or kinder, or more successful or whatever. The funny thing about relationships is that the qualities that people tend to see in others are mostly subjective and they are not static since people are constantly changing.
I am not with the woman I am with because I completely adore her and happen to think she is an amazing human being and one of the kindest, toughest, and certainly the most conscientious person I have ever met. She has a lot of good qualities and even some bad ones but I am not with her because of some quantitative or qualitative assessment. I am with her for one very very simple reason. I like who I am when I am with her.
