I don't believe in love.
Or at least I don't believe in unconditional love (unless for your DC) - as far as I can see most relationships involve romantic love, which quickly changes to anger and hate as soon as someone doesn't live up to your expectations - which really makes relationships a lot of hassle.
I seem to be the only person I know who is honestly happy being on their own, and really, really don't need someone to 'make me happy'.
I feel kind of liberated by it, or do you think I'm missing out?
