I've seen this comment around here before - that you can choose to love someone.
If you're thinking about a quote I had in mind (from a post by someone somewhere in TAM), if I remember correctly it says:
I do ponder about this too. The majority of it is true (love is actions, etc, etc). I can see that I am not feeling butterflies in my stomach anymore after say 1 year into marriage, but I still care for the wife (decide to engage in actions that show love).
Maybe it can be negatively proven i.e. "you can decide not to fall out of love with your partner" (something that cheaters fail to do).
(A=you love, B=you act lovingly) we can write it as
A => B is true (you love then you act lovingly)
not(B) => not(A) is also true (you don't act lovingly then you don't love), but
B => A is not always true (you act lovingly then you love) -- just basic math logic
Something like that....
HOWEVER, I have seen anecdotes across cultures that say if someone is with somebody long enough, there is for certain love to grow between them.....
"Witing tresno jalaran soko kulino"
(Oh, wait, that is a very old Javanese proverb) and again, logic goes to trash bin.
Something to think about for sure....
