Hi, I have never posted on anything like this….But, I agree after having been through this for six years of the disappearing and apologizing.  Sometimes not even bothering to apologize.  That the pattern will not change.  I never knew if my ex would disappear to cheat; however, I have never received a truthful explanation.  Don’t return the message.  I am just starting today with no contact.  And hope that I will not be weak.
