Hi. I usually just read and hardley ever comment but I just felt the need to respond as I didn’t see anyone address the question from my angle. when I got married almost20 years ago, I naturally assumed that I would call my mother in law, “mom”. I felt thatit was proper. however it wasn’t long before I realized that my mother in law didn’t view me as a daughter, only a daugher IN LAW. She would frequently hold “Daughter Only” get togethers, outings and trips, to which I was not invited. No need to go into the details. Suffice it to say that I felt very odd calling this woman MOM, when I was told very clearly ( no offense ofcourse) that I was only her daughter in law. As to what I do call her, nothing really. I try to avoid it as much as possible.
