Ds 4, came home from his dad's very sad and clingy and grumpy. He told me that his dad had been cross with him and had threatened to leave him at the petrol station forever and that he would have to live there. He said "I'm not sure my dad is my best friend anymore' I explained that his dad didn't really mean it and sometimes people said things they don't mean when they are cross. He is finally asleep and I'm fuming. Should I just ignore this? His dad had a mean temper towards me, the main reason we split, and I worry that he will do the same to our son.
