As for your wife and your impatience with her not being willing to have sex with you right now, have you bought about what you would do if your wife had a medical condition that meant she couldn't have sex for an extended length of time? How would you treat her? Would it help you not blow up in your current situation if you thought of your wife as having an emotional condition at means she can't have sex right now?
