Girls want nice guys, but instincts tell them to go for jerks. Sorry. Theres plenty of girls that finally overcome instincts and use their heads more.
Guys well, guys are just pigs that primarily want sex first and mental stimulation later... maybe. But eventually they get over that and find some lady that they can be happy with.
Love... depends on what you consider Love. Is love the giddy feelings of hormones or is love that right person that makes you feel better because they are the right person for you do to personality.
Yes I'm in love because we share interests and differences that let us work very well together. After 12 years I still get the giddy feeling :P
