ok, my mil is crazy. my husband and her just exchanged words two weeks ago. he cried in the car saying he didn't have parents and so on. so now she calls asking for not only one kid but both. my husband was the one that brought it up they didn't have to see the kids again if she wanted to act that way in front of them. I just don't really want them to go, but I am torn because it would be nice. I want to stand behind my husband, but I feel everything is being sweep under the rug and forgiven? or am I wrong?
