The love of ur mom to u: unconditional love: She wont expect too
much, happy as long as u can take care of her when she is old. She
only have few children, including you, irreplacable children
The love of ur gf/wife to u: conditional love: She want to marry
u... IF you take care of her, shower her with gifts and romances,
suffer because you will get her pregnant next time... She has lots
of options and you are one among the options... If she's not happy
and dissapointed too often, somebody will replace you.
