What do you do when your best friend ignores you for his girlfriend and doesn't talk to you at all when she is around?

Might be because his girlfriend does not like u and tod your best friend not to talk to u or she would break up with him

Answer

The girlfriend is the focus of his attention, is all. That is, unless you are another girl, which might cause problems. Allow him his time to be human and give him space. Eventually, he will not be so preoccupied.
