Have you considered going to the home, maybe even ‘accidentally’, to be there when your son-in-law comes home or sometime after he comes home calling him? Or telling someone close to him so they can be there somehow for support? I'd guess you have but have you even begged your daughter to try counseling and pleading with her that this isn't the way to go?
In any case, Your son in law and the whole situation will have my prayers.
Shes in a good place staying either with us or her brother and shes also emotionally devastated so of course I feel for her. My issue is that hell be alone when he reads her note and realizes his life has changed while shes surrounded by her loving family. Im trying to stay out of it as much as I can, but that doesnt mean Im not supposed to care about BOTH of them.
Thank you, bramps.
