I am so sorry for the loss of your brother.
I can related to the hatefulness of the left.
My own 36 y/o son, home-schooled and my pride and joy, has not spoken to me since the night before the election because he rightfully thought I would vote for Trump.
His elderly father, 83 y/o, is in the hospital for the second time in a month, and not in very good health at all. I texted to ask if he wanted updates on his father’s health with no response.
Ironically, his leftist girlfriend posted on her Facebook page how awful it is for parents to be separated from their children at the border. Go figure.
Keep your son updated on his father
Had similar situation
If he knows whats going on, he can decide to come visit
or not
So keep talking even if its one-sided
God Bless you and your husband
