WHAT YOU ALL THINK ABOUT THIS "FALLING FOR A FRIEND" READ!!!

For the past 9 months Ive been sleeping with a friend from school. Over these months weve gotten really close. Hes been the man in my life my confidant. Im starting to have feelings of love. Well on the last 2 months hes been diagnosed with a rare form of cancer. Hes been going through hell but Ive been there for him.he has a two year old son and after being diagnosed he proposed to his sons mother....I was upset but didnt show it. After finding this out i still sleep with him we still converse daily. What do u do when you know loving someone will hurt.
