My ears have so enjoyed not hearing her ex's name over and over and over and over again...
Good plan. I was in the infancy state of a relationship recently and SO kept getting upset by text messages from her ex. I gently suggested she stop having non child/finance communications with him. At that point she got mad at me for implying she was still hung up on her ex. I ended the relationship at that point. I will not put up with that.
I think the end of your relationship with her was LONG over due. Onward to a happier life.
