There is no requirement that you do. I’m completely unsure why people believe that you must allow shitty human beings in your life because they are family. Fuck that! Allow people in your life who make your life better. If that’s family, that’s great, if it’s not family that’s completely ok also.
Does any anyone know the actual accusations? There’s no meat here just the allegation. How was his DD-214 altered? What service did he ascribe to himself? What awards. As the husband of a Soldier, these things are important.
Edit to add: they really need to update their stock photo, the Army hasn’t worn that uniform in years.
