Q : I want to support my treatment cost by getting compensation from the woman having an extramarital relationship with my husband by a suit. 

A : You must not think of any of that. Treatment must be done only for your recovery and happiness. To sue the woman after you have the ability of happiness through treatment is a different matter. Therefore, you must not think of suing her and demanding her compensation for your treatment cost. If you do so, the sue is going to be nothing but for making money; it should be done with a smile and a relaxed mind after obtaining the ability of happiness. You can make a precise judgment only after you become treated with regard to all of these.
