Even though he blames you, to think of you with someone else will massively dent his ego and hurt his pride.
Hinting at this with a car on the driveway, flowers, new hairstyle, makeup and clothes plus XL condoms on top of shopping would wind him up (much to the delight of many of us) but might make things worse for you.
He doesn’t like confrontation. He didn’t like your mum giving him a hard time. I appreciate she is doing her best to avoid him but would she answer the door to him on one unacceptably early drop off, smile sweetly to unsettle him, to make him less inclined to repeat his twattish behaviour?
He also doesn’t like feeling as if he’s an outsider. Make sure you take photos of your DD’s first day at school. If he turns up, deliberately don’t include him. I bet your parents, if they’re there, would do the same. Sideline him. He hated being on his own at a previous event when you stood with your dad. (I’d be tempted to casually drop in a remark about how proud she is of her uniform then look at his half tattoed arm but then I am petty.) If he isn’t present, send the photos to him via WhatsApp, as a happy record of an important day he unfortunately missed (yes, I am being sarcastic) - more grist to the mill.
