good point for long-term relationship

#1 is choosing the right person
It's not about looking good, or having money, or good job, or good sex, or whatever... those are IMO the most important things, more or less in order:
1: Trust; you have to figure out as soon as possible to what extent you can trust that person.
2: Common interests; you have to have a number of things in common that you like to do, so that you'll never be bored together. If you're bored, then you'll start spending more and more time apart, and that means eventually one of the two finds someone else who is more compatible...
3: Understanding; every person is "different", has his or her own special little things. If each one understand how the other's mind and heart "works", if you can tell when he's in a bad mood and what's the best thing to do when he is, if he can tell when you need company and when you need time...
4: Commitment; both parties need to be in good agreement what they want from the relationship. I'm not talking long-term, but immediately; are you planning to spend the entire weekends together like Eva and I do? Or just go out for dinner once a week? Or do something pretty much every day? Do both people expect sex, or neither? (If one expects sex and the other expects no sex, you're in trouble, it won't last.) Do you want to go together every time you go out, would for example you be jealous if he went to a BLUG meeting without you, or will each one more or less keep a separate life?
And of course, 5: Love ;-) if you're both completely compatible but you don't feel anything special when you're next to him, then it's not going to last too long...

Sometimes it can be fun to have a short relationship where you don't trust the other party too much, if you're not expecting it to last... but only if you get in it already expecting it to end... personally I prefer more serious relationships

Most (not all) great-looking guys are jerks, because they know they can have girls easily... and most (not all) great-looking women are stupid and boring because they know they can get whatever they want only with their looks (and sometimes with some guile)
Besides, when I'm in love with a girl I always think she looks amazing ;-) so that's never been a problem for me
