Can a person fall in love with NOT like minded person ?

Yes, They think they complement each other. Sometimes it works. Most of the time it doesn't end well.

Opposites attract they say

Of course they can, keep being in love is the issue here. Somehow they realize they are not for them, when all the passion is gone.

Yes, they can

Yes

Maybe in innocence.
Maybe in the image of that person.
One can also be fooled.

Yes but I don't know if it works long term
