DAE resent their divorced parents for shit-talking one another during your childhood?

My (37m) parents got divorced in the mid 90's when I was about nine and my brother was around twelve. The resentment they felt toward one another (especially my mom's resentment toward my dad) was palpable throughout my child and adulthood.

My father passed away earlier this summer and it's been tough dealing with his death during the holidays. In recent months my mom has started ramping up the shitty comments about how he didn't do this or that and how he was a bad person who failed me. Shortly before he died she told me that he'd tried to hire a prostitute when she was pregnant with me.

Why the fuck even tell me that? It feels like she wants to remind me that she's the only parent I had who actually cared about me. He had his shortcomings, and I have a lot of negative feelings toward him, but now he's dead and I'm trying to make peace with our relationship.

DAE/Has anyone else faced something similar? I see the manipulative aspect of it now that I'm an adult and it makes me strongly repulsed by my own mother.
