This is kind of vague, but you feel she is an addict so I will assume that there is behavior that is causing you to provide sex more than necessary? Has she been a sleep around honey to others? Too much toys not enough you loving? In a marriage sex is definitely between the wife and husband for those who want it too much or not enough then make sure there is nothing there like being a survivor of sexual abuse or anything else. I mean who is the say that too much is too much or too little is too little. How in therapy is someone going to tell you if you ain't getting 3 times a with your depraved! I'm not sure what my stance on this is. I read that there is not such thing a sex addict, but obviously if you had wrote she is cheating with others or via toys/porn and taking away from you then I totally understand. Make sure you not no abusive husband cause her to take her needs else where and feel unsafe with you. That is my personal story....
