Ok I've heard so many positive things about the freedom programme now so will look into it.
So today I had a bit of a rattle. Don't want to give details but his message seems to have been designed with the sole purpose of attacking, accusing and upsetting me by blaming me for his waning relationship with his children. Either that or he genuinely believes he is a god-like figure because he supplies the money and should be worshipped at all costs, even by his children who are obviously too young to appreciate that.
Anyhow the usual pattern ensued: red mist, rant, draft an angry reply back, offload to a few friends, cool down, ponder how best to reply, have eureka moment, delete waffly draft, reply calmly with a fist pump and two fingers up.
So my conclusion: whenever he winds me up, whether deliberately or not, the key is NONCHALANCE, not to appear bothered or ruffled by it, feign ignorance of what he is attempting to do and to not to fall into his trap.
He may well come back again and try to press another button, but I'm confident my tone and coolness is absolutely faultless - because I've done NOTHING wrong! Accuse ME for his failings as a parent? Accuse me because his children aren't falling at his feet with admiration and adoration? Piss off.
