To be honest, a lot of bulls are not husband material. They may offer women a good time but women also want financial security and being treated respectfully outside the bedroom too. There's a reason why those men she's fucking are mostly single. Either they choose a bachelor lifestyle or they can't commit in a real relationship. Any woman that leaves her husband for a good time is doomed to fail. You had something, despite your sexual short comings, that made her fall in love and marry you. I'd be more threatened by a married black man because at least he made it that far.
