I know the OM is not "the problem," but his leaving HAS to be part of "the solution."
OM may or may not believe that she is committed. I am confident, though, that he believes that he will be able to keep her attached to him for the next two years through phone calls, letters, email, and visits when he gets leave. He believes that she absolutely cannot resist him or really live without him ... after all, she's tried to get rid of him several times (to do "the right thing") and she has never really been able to do it. When she sent him away from a week and a half two months ago, he was constantly on the phone, telling her that she couldn't live without him.
Understanding the sitch helps me plan. I'm really glad to be disabused of my thinking that W might be ready to work on a reconciliation as soon as OM leaves. I'm very excited about getting my own apartment and being able to woo my W without my in-laws around (as wonderful as they have been).
The LORD is near to all who call on him, to all who call on him in truth." (Psalm 145:18)
