I've a best fren which is male. At first i thought we really can work it out since both of us sincere & comfortable click as close friends, we almost share everything daily. and 2 years after he got promotion, he made busying with his work an excuse, so end up treat me like stranger after all.

Friendship between male & female, i believe some happen success out there, but i would not try again, like me kinda sad for my situation.

Good luck to you
