I had a friend for many years who made negative comments about infertility treatments and pregnant women over age 40. (I probably shouldn't post her comments here because some of them were quite disturbing). She also did not want children herself, and did not understand why anyone else would. I don't see much of her any more, and she still doesn't understand why I avoid her. I don't even acknowledge her birthday anymore. I am just done with people like that. I have better things to with my time than exerting efforts into managing their toxic behavior.
