ugh, this kitty wants to knife me?

my girlfriend's cat cannot stand me. he pees on my pillow whenever i
visit and jumps on me at 5 a.m. while i'm sleeping. believe me, i'm
trying everything to be this cat's best friend: i buy him toys and try
to play with him, feed him, pet him etc.

if anyone has ever had to deal with this kind of love triangle, can
you tell me what you did to improve things?

thanks in advance.
