Especially for those who don't have kids with your ex, do you still maintain any kind of relationship with your ex-ILs? I exchange holiday cards and sometimes birthday cards with my ex-ILs and ex-grandparentILs. I - obviously - am getting remarried and recently found out that my ex is getting remarried next year. I wonder if it is inappropriate for me to stay in contact now that there will be a new wife in the picture. I do not want to be disrespectful of my ex's new wife. Perhaps I'm overthinking (as usual!). TIA!
