I've been married a little over a year and my wife suddenly lost all interest in sex immediately after marriage. Before marriage it was a few times a week, after marriage 2-3 times a month. She obviously was pretending to like sex more because she knew sex is important to me, but counseling has revealed that sex never was important to her, and more importantly it will never be important enough for her to please me. Ever. Within months after marriage I was tempted by the thought of an extramarital affair and this rate that the temptation will never go away.
I see now that it was all an act because I brought a house and assets into the marriage, and she has brought nothing but debt.
I want a divorce and want to lose as little as possible because of how she tricked me. How should I go about this and what grounds for divorce?
