Me, I've basically sworn off relationships. It used to be that I could share our mutual passions of smoking pot and drinking, but sober it's not so easy, and I turn into one of many operatic characters (most recently Mandryka from Arabella) when I'm attached. Brings out all the worst in me, and every relationship ends in death or breakup, and longevity is no guarantee: my parents were together 27 years before breaking up. I've been in enough that I know the general contours and they're not good.
Also, while I have an intellectual idea of what being lonely feels like, as far as I can remember I've never actually felt it; and also I'm a thousand times happier and much more productive since I stopped dating.
TL;DR (1) my neuroses essentially rule out a healthy relationship; (2) mentally I'm much healthier single; (3) I don't mind being alone.
But good for Trung! I hope you don't mind all the shit I give you.
