In love with my best friend

I think I am in love with my best male friend..but he is not like me..and offlate he has starting avoiding me...this thing is killing me like anything..always now and then I am thinking about him and I cant share my feelings with any one :(..I dont know what to do??...Please some body suggest me how to overcome this..I have tried every possible solutions..from gifting him costly gifts to working for him and listening to his orders...nd the only thing I want from him is to atleast be my friend and stop ignoring me...he only talks nicely when he has got some work to be done from me...rest of the time he does not care..I have lost all my friends..and I dont feel talking to any one else...I used to be so happy when I was not in love with him...
