I think Steve means that you can either wallow in the pain you're feeling or face this head on.
As much as you want to cry great big tears in front of your H, do not do this, Luv. Let him go without a fight, so to speak. You will feel a million times better for acting this way and of course, you will be the pillar of strength for your children.
Has he made plans to move out? You should not move out, Luv. It's his decision to leave so he can do that.
Praying for you and your sitch, Luv. Big big hugs!
