slendercat, I think you misunderstood my post - or perhaps I didn't
explain fully (more likely the case!). I'm not saying that we shouldn't
want reliability, faithfulness and availability, but if someone was
constantly all over you, "I'm here for you anytime - ALL THE TIME" and
was calling every 5 minutes, doing everything for you, never letting you
do anything for yourself - wouldn't that get suffocating?

I think the "nice guy" syndrome is just that - it's doing TOO much for
the other person, and never "loving themselves" first. Not that they
should ONLY love themselves (we all know that type - male AND female),
but if they go the opposite way and put every last bit of their energy
into you - doesn't that become too much at some point? There's no
mystery, no, "I wonder how much he really likes me?" butterflies and
such, because the "nice guy" makes it plain from Day 1 he'll do anything
and everything for you.

That's not confidence. That's not loving oneself. That's desperation.
I can't think of too many people that like desperation in their
relationships.

Hope I've clarified that somewhat.

Because a nice guy is "easy to get". Bad boys make themselves harder to
get.

Think about it: If you go shopping for a car, do you want the $5,000
used car that will still get you from point A to point B just as
reliably, or the $40,000 red sports car that you know you really can't
get but want badly anyway? Most people WANT the sports car that they
think they can't have, even though the used car still does the job - and
may even do it better by using less gasoline!

Same principle applies to relationships. Not that you need to stop
being nice, just stop being available to anything and everything for a
person. You make it too easy when you'll do anything for someone. Make
sure you do some things for yourself too. Don't be a jerk about it to
the girl, just say, "I'd love to do XYZ with you (or whatever), but I
just can't this time. How does next weekend sound?" or "How about
tomorrow instead?"

Of course, don't do it every time and with everything, but if you make
yourself so available that you 1) forget yourself and 2) don't make
yourself at all like the red sports car to her, then she'll see you as
the $5,000 used car. Does the job, but she's just not interested.

Make sense?

Most scholars no longer believe that Moses wrote the first 5 books of
the Bible, but rather that there were 4 separate authors (possibly a
5th).
