Well if you asked my ex-husband whose fault our divorce was and whose fault it was that our marriage was sex starved, he would say that it was 100% my fault and 0% his fault.
Yep, after many men get married, they stop 'courting' their wives, become wrapped up in careers, and become lazy about maintaining that emotional connection that their wives need to stay physically close.
