I am sure that this is the right thing for you to have done but you havent rejected her! sex isnt everything is it? most married couples stop having sex at some point in their relationship (I know lots of people who sleep seperately from their wives but who still love and need each other) and so I am hoping that you too will stay together for many years to come but I guess it's over to her now. Does she want children by the way? do you? have you thought of adopting?
