Would you be depressed if you found out?

I wouldn't blame anyone at all if that happened to them! And yes, that would make me depressed. But, as they say "there are plenty of fish of water", don't let that one person ruin your life. Maybe one day, that person will care for you and will regret that they have never even paid attention to you, but by then it might be too late. Who knows? I'm sure everything will turn out though :) I hope I helped and good luck!
