seriously somewaterytart, you would do it for your sister, mother, a friend or anyone if you were worried about then and realised what was going on. It is not giving in to anyone.
I think, if I was 100% sure that the only possible way of getting my mum or sister away from abusive partners was to endure a few visits and civility with him, yes I would do that.
However, I think the op may not be in the position of strength to do that.
Her mum has allowed her partner to be unpleasant to OP's children, she has had a go at the op for calling him out for his behaviour. Yes, this is possibly just the result of her relationship with the partner. But for the op, to be on the receiving end of this from her mum, while she is pregnant and maybe feeling a bit vulnerable; that must be very hurtful and unsettling. This is nothing like a daughter or sister lashing out. When your own mum does it, there is an edge to it I think, because this is the woman who is supposed to care for you more than anyone.
Basically, it is a lot more complicated than, "what you wouldn't go round a few times and be nice to this cunt, so your sister or mum could be out of the relationship?" isn't it? It's never just a few visits and niceties. This could go on forever. At what point can the op not be held responsible for her mum's terrible choices, much as I feel sorry for her mum and don't necessarily think it is her fault. The op has to take a stand at some point and not let her dcs fall prey to this man and her mum, who is complicit, whether that is her fault or not. She has done this now and well done to her.
Not an easy thing to do at all and I expect the projection and undermining that some people have decided to engage in on here has not helped at all.
