i know this is hard to explain and even harder to understand if you've never been there... but sometimes you really do feel a relationship isn't right from the beginning. but you don't really know that at the beginning. like, you buy a shirt: it fits wrong, but you love it, you feel you can grow into it, you tell yourself you'll get it tailored. maybe it's not the most flattering color, but who cares, there's no rule about what colors you can wear. besides, you searched for that shirt for ages, you spent a lot of time and money on it. and you had a really great time in that shirt once, even though it didn't fit. and once you give it away, you look back and think, "god, that shirt looked awful on me."
