When I met my husband, his ex wife (they had been divorced for three years at that point), used to call him daily. She very rarely shared things of use about their two children. More often than not, she was calling him to either complain about how hard her life was, to tell him he was a terrible person, or just to have someone to talk to. I should add that she was already remarried at this time. Early on in our relationship, I pointed out to him that he still essentially had the same relationship with her that he had when they were married and he agreed with me on that point. I told him that I wasn’t interested in being in a relationship with someone who was still in an emotional relationship (even if it was a negative one) with another woman. At that point, he cut off most communication with her really fast. As further backstory, she was abusive to him during their marriage and her communication was just another way to continue the abuse. Many counselors would say that if you feel the need to be in contact daily, you haven’t moved on from the relationship, so it seems like your ex wife has not totally moved on. You’re divorced, so you have to give one another emotional space to move on from the romantic relationship between the two of you. As someone who’s gone through breakups without children, I know that the only way I moved on was when I stopped trying to be “friends” with the guy I had broken up with. I know it gets messy with children, but keeping up the same emotional habits with an ex doesn’t allow people to move on. If you’re divorced, presumably, you both wanted the relationship to end and you both have to let it end and enter into a new relationship that is just about parenting your children. Also, if you want your new relationship to work, you have to make sure that you are not playing the role of emotional outlet for your ex wife, because that’s emotional energy you should be giving to your fiancée. My advice to you would be to not respond to anything from your ex wife that does not involve your children and keep your responses to anything about your children, completely transactional.
