Hey bro whats up?! Listen man ive been in similar situations...the problem didnt start with doing AS or anything, the problem arose when u decided not to drop your ex. Look we are about the same age and from my experience with women an ex is nothing but a rotwiler on a thin and tattered leash. They act as though they are loyal to you but the second you fuck up that loyalty snaps and they will betray you without even thinking about it. I can see why that guy is insecure, you cant blame him. I dont know how you got in a situation where ur training partner is boning your ex, but shit like that has only lead to fights with me. Its none of anyones fuckin business if u use or not. But i dont think fags with unstable personalities should gear up. Like that guy hahaha so as long as hes not using, fuck him. Just deny it if anyone accuses for law purposes haha.
