Threads like this always make me feel wretched and gutted.
Not because I'm not happy for all of you who are in such great relationships, I am, and wish you all much continued happiness.
I don't know if I believe in "the one", I see things more in the same way as The Armadillo I guess - if I was in a relationship like that, I'd be ecstatic.
My husband feels like my housemate with shared childcaring duties. Things aren't awful enough to split up, but it's not a marriage. I can't knock how hard he works, and that he is useful to have around - and I'm not exactly the ideal woman for many reasons - but we never have sex, we're not really friends, we'd never take an opportunity to spend time alone together.
I always feel like he has no respect for me, finds me physically repulsive, generally looks down on me. Now and again he will say that he's in love with me - but I don't believe him.
He often says that I expect too much from the relationship - that we are like most people - but if I am to take this thread as an example (and what my friends tell me about their relationships), it looks like most people are extremely happy in their relationships and we're in the minority.
