I've been living separately from my wife for years. Since then I've been having sex with other people's wives and paying whores for sex. You can get used to this too. Köbling Tamás
It may be cheaper to keep her. Besides marriage isn't always about sex. While I don't live separately from my wife we don't have sex anymore. She's still my best friend but when I want to fulfill my need for pussy I get it from other women.
Here is the bottom line. This woman is not willing to accommodate your needs. In a marriage we are suppose to take care of each other. We are suppose to do things to help our spouse in life -- she is not wiling to do that. Three reasons why she is not willing to help you in life. First all her needs from you are being taken care of. Second she does not care about your needs. Thirdly she knows you will not divorce her. You have two choices. Bite the bullet and divorce her. Continue to live a miserable life. It is your choice.
Well, you have to decide if you will be more miserable with her or more miserable living with only half your life savings. Cheaper to keep her. At least I get my weekly....
