Anti Wedding Cards Messages What Do You Think Of An Ex-wife That Sends Anti-versary Cards?

What do you think of an ex-wife that sends anti-versary cards? - anti wedding cards messages

I know a man who receives a card anti-sary each year of their age wedding day. He and his ex do not agree at all, but are still in touch because of the children. Both are in relationships with others and have been for some time. What do you think of their behavior? How do you respond?
