How can I avoid him without avoiding my other friends too? :/?

I am new to yahoo answers. But i have some experience behind me like you. I read your previous questions. From my experience, i can tell he is a very weak person either seeking deep friendship or is loving you and waiting for your response. Sometimes friendship can go ual way also since it is also based on physical attraction. Be courageous and tell him about your situation. If he cannot hurt you since you have a tool for blackmailing- he fingered you. Be practical. Get the problem solved now itself. Avoiding will cause problems only since you are physically attracted to him.
