Then don't call them. The best way is to omit this link, or just call one without calling the other. Real case: the bride's parents divorced and returned to their hometown to hold a ceremony, because the groom's official is from other places, which is equivalent to holding another wedding in the local area. The bride's parents are here, and her mother is nothing, because her daughter grew up with her, and most of the people present are her relatives and friends. So that day, from beginning to end, the bride's father's face was always tight. After introducing the ceremony, his father ran to one side to smoke, and then left without even eating.

So a situation like this is very difficult, because the wedding company, he doesn't solve family problems. But you'd better not invite them both, because it's better not to let him come than to make him feel bad.
