I'm not claiming to be an expert here but maybe its time she was in her own room, maybe she'd settle easier with less distractions and maybe get a longer sleep at nightime. Am gets put down after shes had her last bottle at half 7, even if shes fast asleep or wide awake, its what the HV told us to do from day 1 so she could learn to settle herself and so far its working. It may take a few nights of tears and tantrums but its got to be better for you all in the long run.
We manage to have a few hours alone each night and too eat tea in peace, I'd say time as a couple is well worth putting the work in. I think you need to give your OH a kick up the bum aswell haha. my OH works 14 hour days sometimes, biut he knows he has to be home to do last bottle and bedtime, and more to the point he enjoys it, its there time together
