My girlfriend of ten years has sudenly become to close to another girl who is her best friend. She tells me they are just close friends. But going through her phone when She was asleep. The other girl suggest lesbian clubs, and is clearly hitting on my girlfriend, they talk almost all the time my girlfriend confessed that her friend is attracted to women too…now my girlfriend has lost intrest in sex, She keeps giving excuse saying She is tired etc… and even if We do She is not intrested. What do i do? Should tell her to stop her friendship with the other girl or i join in and encourage her We hang out three of us.
