You're doing good, Frank. She's watching you very closely. Looking for one tiny thing that will justify her wanting a divorce. That's why she asked if you had been drinking. Good job handling that. Smelling milkshake breath might have been gross but at least it removed all doubt!
I'm so sorry about your friends losing their son. I have prayed for them since reading your post. I've kept you and your wife in prayer, too and will continue.
