All i have to say is you live once, and if you really care about that other person you should let them know before its too late. I am in the same situation right now but i am scared to talk to my ex about us, we talk normally at work and in person, but i never bring up how much i care about her still because she was the one that broke it off and wanted me in her life still. It sucks to not know as well. you can talk to me on my email if you want because i feel like we have the same kind of questions and might be able to figure stuff out. I have talked to so many people and I am just as lost as the day we broke up.
