My ex talks to my son on the phone. He hasn’t seen him in a month, they speak occasionally maybe every couple of weeks. The thing is he keeps making plans to come and see him then not turning up. He’s done it again this weekend, told my son on Tuesday he will come down to see him this weekend then my son hasn’t heard from him again. Will this be “good” for my son so he can see what his father is really like? So he can’t blame me for anything? (Been told this is a good thing)
