My ex was abusive and my mum never shuts up about him!!!!!

We've been broke up for nearly 8 months... She's constantly telling me to watch myself cuz he might do this.... telling me who he's friends with so I can avoid them.... telling me about what he's driving where he's living.... talking about him maybe showing up at the hospital while I'm in labor.. (which my midwifes etc know not to allow him anywhere near the hospital or the police will be called) blablabla she's only looking out for me obviously but I'm sick of hearing his name... She's more obsessed with him than I was !! Like how am I ment to move on whenever she's constantly bringing him up.. I think it's because of the stuff he's done to me in the past it always plays on her head but it's annoying ASF. I've told her many times I don't care and she's stops the conversation but it dosnt stop her bringing up another topic about him a few days later.
