Bored, what do you mean exactly? I assumed you were speaking of love as a feeling, but maybe you are defining it differently. Your actions are clearly a choice. Your emotions aren't.
No Vermouth, I am speaking of love as a feeling but I am defining it differently. Though, love for ones children is not the same as love for a spouse. This, I believe is instinctive. However, love for a husband or a wife is something of a choice in my opinion. It is not a real emotion. I still call it love, but it a choice as is homosexuality. Certainly not something that one is born with.
I first heard this about 8-10 years ago when a woman I knew was getting married said this. She had been counseled this during a class that the church gave to all couples planning to marry. Instinctively, I didn't believe it but after much thought it made sense to me and now I'm in agreement with it.
