are u serious dude??
how does ur not responding to her advances imply that ur not man enough aka gay!!??
im seriously blown away by u even implying it or questioning wat u had to do
u love ur wife... another woman tries to hit on u... u tell her to piss off.. or if ur the polite kind... u ignore and walk away.. and not care wat ppl think coz ur respecting ur promise to ur wife
and ur friend.. not much of a friend if he's encouraging adultery in any form.. wthr u went home with her.. or simply bringing someone along to hit on a married man..
i suggest u re-evaluate ur friendship with this guy.. and avoid these kinds of awkward social situations since there mite be some temptation of any sort..
so - keep loving ur wife
cut off ur friend - or confront him so that he realizes wat ur boundaries are..
and just stay the way u are.. respect! (u aint gay!!)
