Ok, so brief background.
DD's dad left us nearly 4 yrs ago for another woman, with whom he has since had a child. He has 3 children by 3 women, none of whom he sees much (ie, once or twice a year). I now live 80 miles away from him and his family.
Before he left me I had concerns about his mental health - he has no ability to open up or talk about his feelings, he was obviously depressed, constantly lethargic, didn't eat much, had strange paranoias (ie being convinced the woman next door had poisoned his cats then made it look like they had been run over on the main road ), insomnia...
Since we split he has basically refused to speak to or see me, but I have been hearing from friends that his behaviour is getting stranger. I have just had his best frind's GF on the phone to ask for his parents phone number. Apparently last night they went to see him, he was taking coke (he has been drinking and doing drugs a lot recently, she says), and then found a dead rabbit in the road and started to skin and eat it raw (he is ardent veggy, has been for 20+ yrs). She said he was incoherent, they thought far worse than drink would render him, and ranting and abusive. They tried to talk to hm but he threw them out saying they were not his friends anymore. So I gave her his parent's number (they know his parents as are v v old friends), and she rang them to try and talk to them about how worried they have become.
His mum answered and insisted he was fine His bf says this is definitely not the case. He is living in a completely empty house - burnt the furnituer on the fire, has no cooker/fridge/bed. Nothing. He doesn't eat, or speak to anyone really.
I am worried sick. He will not speak to me so I don't know what I can do, but his friends are concerned (as am I) that he is so unbalanced/delusional/paranoid he may harm himself. Does he have to ask for help himself or can we get him any? Whats the best way to help? I cant bear the thought, no matter how badly we have got on in the past, that DD may not have him in her future. She needs him.
Part of me wants to go up there now on the train and give him a hug and cook him some dinner, and try to talk to him. I know he wouldn't even let me in.
