I love her, but I don't know how to tell her.

How can I reconnect with Tiffany and tell her what she means to me without feeling like I am making the possibility of losing her more real?

Tiffany, my sister-in-law, feels like the other half of me, but she has cancer and we do not talk much because life is complicated. I am afraid to tell her how much she means to me because I do not want to lose her.

How can I tell whether leaving is the right choice when I still care about her but feel that my efforts have not made the relationship feel close or mutual?

I have been trying hard to make my girlfriend happy for about a year, including spending money on gifts and activities, but I still feel lonely, shut out of parts of her life, and unsure that she really knows or wants to know me. I am now wondering whether I should leave.

I've loved him for three years, but he has a girlfriend. We graduate tomorrow—should I tell him?

I've had feelings for a close friend for three years, while he has had a girlfriend throughout that time. We graduate tomorrow and will be going separate ways, possibly never seeing each other again, and I have repeatedly written and deleted an unsent confession.

We both have feelings for each other, but too many factors show that we can't be together. Should we keep things ambiguous?

I live in a different city from a woman I spend hours talking with every night, and we have a close romantic connection. She plans to return to her hometown for her parents and a stable job, while my career and family situation keep me tied to a major city, so neither of us expects to relocate.
