just over a year ago, my BIL, so DH's brother, announced he was leaving his wife of 20+ years. He had fallen out of love with her several years ago, and now he had a new girlfriend he had met at work, decided to throw in his marriage. No children involved. I am civil and polite to him and his new partner but I admit I am not my usual warm can't-do-enough-for-family self. I like my old SIL. We exchange birthday cards and christmas greetings. We, DH and I have been out for dinner once with her since her marriage breakup. I have called her a handful of times. My ex-SIL is suggesting a meet up again. I like her. I want to meet her. I'm pretty sad she won't be godmother to my first child who will be born later this year. But I don't want to cause trouble and ill feeling in DH's family. So far no one has commented to me, i also haven't proactively mentioned it, and DH is up for going out for dinner with ex-SIL again. Should I let the relationship fade out to keep the peace?
