I’m glad you sorted out the immediate crisis that your dh had caused.
I am worried that although it sounds like he won’t acknowledge what he has done to his son (or to you), you are all too happy to try and cover up what he has done and smooth it all over... because you can’t really, can you? No matter how much you want to.
You can’t give your DS his dad back. Only that man can start taking responsibility for his own actions, stop relying on his own wife and son to absorb the emotional damage and physical difficulties he puts them into... and sorts himself. Only then can your son have his dad back at all properly.
Until then you’re all just pretending.
And I’m afraid the odd good moment does not outweigh the underlying fear that your son must live in. Because he can’t ever trust that he’s going to get ‘his’ dad, or whether his dad will selfishly decide he loves the drink more than he loves his son in that moment.
And maintaining that climate of fear is no kind of life, and is no kind of childhood.
Would your partner bother to keep up visits to his son if you did split up? Or would you get left holding everything and neatly being the bad guy?
I think you need some counselling to get through this. Perhaps family counselling?
I know you’re minimising it all and probably the discourse of ‘it’s a disability like any other’ can come in handy to do that. I saw it in a previous post. But I’m very seriously physically disabled, yet pour every ounce of my physical and emotional being into creating as good a childhood for my son as possible. Everything is about doing that. So it gets kinda tricky when people lump addictions in with all other disabilities, as quite clearly your dh isn’t doing anything at all similar to me and thousands like me with physical and mental disabilities but whom are still 100% focused on our children. As he is so selfishly focused on his relationship with drink and what it gives him, he quite honestly doesn’t give a f*ck about his family. Who the hell walks away from your child with an, sober, and decides not to bother carrying on being a parent. Who opts put like that?!
Not to say he doesn’t deserve help or sympathy etc., but it’s not the same as so many other disabilities. It just isn’t.
