how do you know if you really love someone?

I'm not so sure there is a such thing as true love, like the stuff in movies and fairy tales. Some marriages have couples loving each other insanely forever, and some don't. At the rate of divorce today and the marriages that don't, that still turn piss-poor after a few years are part of the evidence.

I've never been in love, but I guess being in love means you feel like you don't want to ever leave the side of someone, and are always happy around them. Also you feel you want to always protect them with your entire being. I really don't think there is much difference in love of a family member and of a spouse except for the sexual attraction part. The love part is probably the same.

Jam it back in, in the dark.
