Falling in love is a mating instinct.... Love is a herd-protection instinct... nothing more and nothing less.... If I fall in love with someone I know I will never have a "proper" relationship with them... I never fell in love with my ex-wife, even though (at the time ) I loved her... i have fallen in love four times in my whole life... the first time ended in schizophrenia, the second with rejection due to inaction, the third fizzled out because although (apparently) she felt the same she was too scared to do anything about it in case she ended up hurt, and the fourth... well, the less said the better, except that I very nearly lost a very good friend, and i'm really surprised that she still has any contact with me... so I now look at love in a purely scientific way.... its less complicated and easier t understand...
