Stop thinking.
You are out in left field where the term "supplanter" is concerned, too. Forget it.

You are supposed to find REST in HIM - so I'm not buying the 'He said no rest' crap.

Something is seriously wrong here...

Maybe try being quiet instead of thinking/talking so much.

That's the only way you're going to find peace no matter what you end up doing in terms of your marriage.

Just shush!
