I have one friend, a very very close and I notice something odd I him. Ever since he was became my friend he never hug me or notice any changes to me until I open something in our circle. He and I are the only guys in our circle and we are 5 in our circle. Eversince I mention to him that I like one girl in our circle, at first he just nod and became silent but after that day he starts to be clingy and became more talkative and possessive. There are time that he hug me in front of our friends but I didn't put malice in that because we are both guys and I think it's normal because I became more close to him. There are times also He sniff my neck but his lips and nose touching it, I hide my reaction everytime and after that he always compliment me (I'm using Strawberry and Champagne by VS) But this is the bomb, one day he ask me to go with him in the seashore to drink, when he is tipsy he hugged me but he let go of me and talk to me some random topic but after that he play a music titled Heather, he smile and sing but he highlighted the words "I wish I were Heather" I know what he mean but we are both Guys, what should I do? Until now he is the same and became more clingy to me.
