I think my girlfriend's best friend (a girl) hates me. She never talks to me in a good manner nor she looks up to participate in plans I make for our group. Sometimes she also instigated a feeking of untrust in my girlfriend because of which we had a long fight. I can't say against her best friend for obvious reasons. I don't know what's wrong. I'm very loyal to my girl. She is also happy with me. I bring gifts for both of them. We hangout together. Still she hates me. Please help me with this situation.
