huge hugs to you

its so hard I know. I'm currently battling with LO to get her feeding, I cannot understand why if she's hungry she comes off the boob constantly and screams. If sit her up or put her on my shoulder for a bit then put her back on the boob she feeds for a few seconds like she's ravenous and then comes off screaming again. Sooooooo frustrated. Especially when she's in full tantrum mode a grabs my nipple twisting/yanking it as hard as she can!!
With regards the wind problem, I find laying LO across my lap so her belly rests on my thigh helps. Its a lot easier too, no arching of the back, not so much wriggling/going stiff as a board either.
I know what you mean about your OH going away. I've had the same thing twice in the past month, though only for 2 nights each. It wasn't as hard as I'd imagined, I made sure to get out so that I wasn't spending all day AND night alone stuck in the house.
Just remember... its only a phase
