I fell in love with my best friend, he is a gay male, I am a straight female. I haven't told him how I feel but it sometimes feels as if he knows and is playing with my emotions. Our relationship is, and has always been strictly platonic, but sometimes he talks about marriage with me. He hasn't been with a woman for 20 years. I know he loves me as a friend but why does he lead me to believe we can ever be more. Sometimes when we are out, usually at gay clubs, he tells people we are married, and sometimes he says that maybe we should get married. I usually play it off as a joke but it feels like a knife in my heart. Any advice?
