The compromise on two nights, but home in time for bed, seems fair to me as long as the OP gets two of her own nights free. I don't know that I'd jump straight to emotionally abusive. It sounds like he's still working on his communication skills and they're not going to magically become perfect overnight -- it takes time. Perhaps he thought at first that one night would be enough, but then found his needs changed. I hope the OP too would be able to bring up a possible change and discuss it with her husband if she felt she needed one, rather than stick to the original plan and feel stifled.
I've stayed out of all of this and the other thread, but if the OP gets two nights on her own, and DH gets two nights alone, that leaves three nights a week out of 7 they are together as a family. They have a child. Maybe that works with some families if that is what they both want. But it doesn't sound like the OP wants her DH to have more than one night alone nor does she want more than one night to herself.
I don't know. I see some people saying here that this might be a temporary backsliding. I see it as the OP's husband tried and it isn't working. Strongarming the OP into accepting what he wants, and on top of that, insisting she not only agree to it but that she is satisfied with it?
OP, I'm sorry, but I think at some point you are going to exhaust yourself trying to make this work when your DH, to me anyway, clearly wants either a. out or b. to do whatever he wants without regard for you or your child or your feelings. I know option a seems painful, but it will be inherently less painful in the long run.
If he's gone, you're alone, but with your freedom and ultimately the option to find someone who will be kind and appreciate you. If he's there, you're alone most of the time, as well as trapped and taken for granted and emotionally abused. I'm sorry, OP, but in your situation, I'd walk away at this point regardless of whatever trial period you've given him. Enough is enough.
