Hi where, sorry have been a bit tied up with work so haven't checked in.
Yes get angry - but remain detached from him and cool and try not to rise to his rudeness.
Of course he is angry with you - you are a living breathing reminder of the shit bag that he is. If you were happy and chirpy around him he'd feel he was off the hook and that he did the right thing by leaving.
You are a relflection of his guilt and bad behaviour.
If the comments are snide then just have a reply ready, " how rude, they are your children too..." and telling you to look at yourself, that made me mad, I would retort that for an old man he has quite a childish attitude.
Then when the dust settles and you can carry out a calm conversation and if you cannot stop him from bragging about his new found freedom or reinvented age
(ffs) then pull the rug out from under his feet by reminding him in little ways of his impending age, hairy ears, saggy butt cheeks, receding hairline, long earlobes etc...
Conversation scenario: there is a twenty year old girl I've met who is so into me.....
You: awwww it must be quite nice to meet someone who can overlook your pot belly/ nose hair/bald patch - as a younger woman I actually found them quite repulsive, but they do say love is blind eh?
You can do this! Now how are the pratical things going regular money in an account from him and a solicitor??
