I think its different because of course we are different, we are older, wiser, sader with more bagage.
I wanted to write that love a second time round is different because the human imperative to mate is gone, and therefore the love is based on a different need.
That need varies from person/couple to person/couple..........and talking only for myself, i dont need someone to financially support me ( i do that myself ) , i dont need someone to do the diy ( my dad does that ) but i need someone to share my life with but not to consume me and take away my independance.
Love is different cos its based on different needs thats all ...................
