It doesn't trigger me, but then none of our experiences are exactly the same, what triggers one person is not true for another. I'm single, been that way since school. I have no plans on dating, but that does not mean I hope others be the same, for some people, romance can be very rewarding and healthy. It just depends on if it happens at the right time and with the right people. I've come to recognize love to be a beautiful thing, and it's really our one chance at happiness in this world. Not all friendships have to be about "being lovers", but it can bring happiness as long as there's clear respect for boundaries in that relationship.
