The reason nobody has laid into the father is because it goes without saying he’s a cunt, and if he were still alive nobody would give a fuck about discussing the why’s and wherefore’s of why his ds doesn’t want anything to do with him, or trying to suggest things to possibly solve it. The phrase abusive cunt would cover it. With op, that isn’t at all the case.
I would also suggest that his bad behaviour is easy to understand. Most teens are stroppy and unreasonable at some point, but with the added complexity of his background, it’s not a wild leap to say that his is likely to be far more extreme.
Also, going from ops more recent posts where she just wants to concentrate on the future, doesn’t really see why she should listen to any blame he might have for her and just wants to explain her side, I can fully empathise with his outbursts.
None of us realise as children just how badly fucked up our childhoods were. It’s only as we get older and get a wider experience of what is normal that the horror actually hits. If ops ds had reached that stage, and the response he got from op was explanations of her side and her desire to move forward, or he already knew that would be the response, it’s not surprising if his way of coping was to bottle it up and then explode.
Also, at the risk of sounding like I’m projecting, I can see his side of the restaurant issue. If he thinks op doesn’t really care because x, being given material things and expected to play happy families in public is an explosion waiting to happen.
Obviously as op isn’t my mother, I’m not for a moment suggesting she doesn’t care and was simply doing it for show. I highly doubt that is the case. But if what he really needed was to have his anger/ resentment heard, and his need was ignored from his pov, I imagine his frustration would be the same.
Essentially op needs to decide whether her desire to explain herself and avoid any possible blame from her ds and focus on the future is more important than trying to salvage their relationship.
