Clair , it all sounds terribly sad for these kids .
The thing is , this didnt happen overnight , it will have been a gradual decline into this sort of behaviour and your P has played a major part in not enforcing rules and boundrys , it sounds like he has been a very very poor father in the past and isnt much better now .
The entire family sound dysfunctional , including aunts and cousins and all this normality with kids drug taking . To someone like you , this is quite shocking , but it sounds as though this is normal and a life style choice within their family . No amount of you listening and supporting or advising is going to change this any time soon . He has very differant standards and boundrys to you , and i dont think this is going to change , or it would have done by now .
I note again your talking about supporting him , what about some support for you ? Who supports you in the midst of all this toxicity where you are being locked in the house and ranted at ? What did your P actually do about this ? He sounds activeley passive when all this is going on .
Im a bit concerned to hear he was still seeing his wife and that he was lying to you . Im also a bit concerned as to the reasons he gives for thinking your incredible , because those are the precise things that are benefiting him directly . It might sound harsh , but his family is in a mess , and instead of laying down some boundrys he does very little but crys to you about it . Its not good enough , hes the adult in this situation and needs to take responsibility and to protect you from any hostility .
The kids have no boundrys , and it doesnt sound like he does either , lying you you , cheating on you , allowing you to be verbally abused , and refusing to set limits , and not being around his daughter when she was small . Why was that ?
You sound a nice person , almost too nice because im fairly certain if you were to split he would not have women banging his door down desperate to be part of this. Think about what hes getting out of this situation , and what your getting out of it . He has somebody to constantly offload to while he does nothing , someone to emotionally support his kids and be theyre confidente because hes not doing his job properly , somebody to worry for him and take off the pressure with all these various problems that hes whinging about but not actually doing anything about . A normal adult does not usually need this level of emotional support . I would also be worried about his capacity to lie and cheat .
I dont know how old you are , or if youve got kids of your own , but life is too short to be a counseller to another adult . Sure we all need a hand hold occasionally , but i simply could not cope with living with this level of negativity , and especially not with a man who is doing nothing about it . Your P , along with his wife , has been a neglectfull parent in the past , and is likeley to continue in the same way.
