Good advice in a recent newspaper article..
Going through divorce is hard and when it’s your child getting divorced you may have to be a supportive parent as well as consoling grandparent. Be loyal. That doesn’t mean condoning or ignoring bad behaviour, especially if this is what ended the marriage. It’s letting them know that you’re there for them, no matter what. You can still love and support them while saying that you don’t agree with deception, lying or nastiness and in taking that stance you might actually be able to influence how they behave. Children first. Sometimes divorce comes as a shock and at other times parents will be aware that their child’s marriage is unhappy so it can almost be a relief when it ends. Resist the temptation to badmouth the son-in-law or daughter-in-law.
