nah...i think he's just scared of his wife. thats why he lied to u infront of her. obviously he's not scared of losing friendship with you, cos he wouldnt do that (sex with ur partner) in the first place. he's old enough to think before act. get rid of this guy, he isnt ur real friend. and get rid of ur partner as well. she did it THREE times! not just once, okay? u deserve much much much better than her.
