Good afternoon,
I am looking for some advice for my DS please. I’m really worried about him 
ExH and I split up when DS was almost 2. When we met exH was from quite a poor family in a deprived area (he wouldn’t mind me saying so) but he has managed to build himself a good career. Unfortunately, with this his attitude changed too. He became a bit of a bully, confrontational, very “billy big bollocks” is best way of putting it! I know he is like this at work but that overspilled in his personal life too so our marriage ended.
DS is almost 5 now, bit of a handful but a very happy, intelligent, lovely little boy. We split custody maybe 60 me/40 him, this is an informal arrangement but has always worked well. A couple of months ago, DS started coming home in the clothes I had sent him (two days before) unwashed then we had had issues with his teeth cleaning, hair brushing, bathing, food.
A couple of times I have dropped him off now, I have felt worried about leaving him. His Dad was nitpicking over little bits, making him stand in a certain way, repeat things, it was like he was in the army. It was totally unnecessary, felt like he was exerting his power of him for no reason, bullying him almost.
Yesterday I specifically asked him to bathed and he barked it at DS like some army general. Today I find out he didn’t have a bath, he had plain pasta for dinner, bread for breakfast today, he hadn’t done his school tasks, his face looked dirty and his teeth didn’t look clean.
I don’t know what to do. I have spoken to exH before about his teeth cleaning and clothes and just get a load of crap excuses. So utterly crap I can’t bear to listen to them again. I also don’t feel like I can dictate how he speaks to DS is exH’s own home and under his care.
I’m so confused and torn. DS loves his Dad and his Dad would never hurt him. His shitty personality of "I am superior to everyone" just always rears its head. I didn’t think I would find myself in a situation like this. I know I need to speak to exH but I am truly loathe to listen to his BS and get in a huge argument.
Keen to hear advice please
