We do not know if she has anyone else to rely on, arthritic. The OP seems to have left the thread.
But when you have HG you are very dependent. This seems to be something that's escaped most people. You are ILL. This is not flu, or if it is it's the real bad version that can put them out of action for months. You cannot do everything yourself. Again, this seems something that people simply aren't taking into account.
So if - IF- she was gonig to leave him she'd have to make very sure that she had enough practical support to simply get through the day. She's well enough that she can manage her job part time, which is great, but that almost certainly takes all her energy and reserves. I venture to guess fairly confidently that for her, it is -either- part time work -or- going shopping everythign else. It's a nasty choice. A lot of people do loose their jobs during HG becuase a lot of employers manage to work around the law.
So she'd need that practical support. Then she'd have to find the emotional strength to end the relationship, not exactly an easy thing even when you are in a position of strength. her partner will almost certainly be angry, upset, pleading, etc etc and maybe would get very awkward. all this takes energy you don't have when you are severely ill with HG.
If she chose to end the relationship she'd absolutely, 100% need intense support and help. There is no choice here. She'd very likely have to move in with her parents, if that's even an option.
Please, arthritic, go and look up what living with HG is like. I don't mean that sarcastically, I mean that to try and communicate what it is like living with it. The actual reality of it and isolation of it. I would -hate- for my daughter to have HG at all. But if she did and if she had an unsupportive partner, then I'd be asking her to move in with me. If for some reason that was impossible then I'd have to say for her own survival and that of the baby, to stay where she was until the baby was born. Some practical help when you have HG is better than no help. Leave after, if it comes to that.
I say again I am NOT in favour of her husband being a selfish idiot. Though he does help a bit and hopefully if something can get through to him, he will improve. But if he doesn't, her life is not going to be improved by jumping from the frying pan into the fire.
Her life is very difficult, her husband's moaning is making it worse but if she is left without practical support it could be a great deal worse. As I said, many many women have had to abort when they have HG and no practical support. We don't know if it would be that bad for her. But ending the relationship is not a decision to be made lightly, and quite a bit of the advice here is missing the giant elephant in the room that she is pretty damn dependent atm.
I honestly wonder where a sense of proportion and a sense of understanding the reality of HG has gone on this thread.
