1. How many times have you truly been in love?
Just once; am knee deep in it right now with Aaron :-)
2. What was/is so great about the person you love(d) the most?
His smile, his laugh, his voice, the way he takes care of me, how he goes easy on me when we play video games, when he pouted when I beat him at speed and he said he wasn't aware we were playing 'prison rules' :-), how he talks in his sleep, and many many many more things I could divulge here, but I don't want to get too mushy :-)
3. What qualities should a significant other have?
Trustworthiness, great sense of humor, honesty, they should be spontaneous, intelligent, etc... what a general question
4. Have you ever broken someone's heart?
I don't think so
5. If there was one thing you could teach people about love, what would it be?
to be patient in your search for it... it's out there somewhere.
