This is absolutely an anxiety/depression symptom, and one I had in a bad way (in addition to the old "can't get enough air" feeling). It was just like you describe it: you're on that fence between sleeping and waking, and suddenly you jerk hard, or you twitch (for me it was any limb, like a leg, shoulder, sometimes even my abdomen jerked hard enough that I nearly sat myself up!). Seems like when it happened to me, I was literally unable to actually get to sleep either for hours, sometimes for the entire night. I could only sleep every other night, on the nights when I was so exhausted, there was no choice.
Oddly, I get the creepy haunted feeling on wake up quite often, even now. It's usually associated with bad dreams though; I have those a lot.
I was lucky--mine is pretty minor now and was only worsened by circumstances at the time.
As for you, your partner needs to shape up or ship out! That is so wrong and sounds completely unsupportive. It won't help *at all*. What you need is to get at the source of your anxiety or depression--a counsellor would help that a lot, and a decent prescription will probably help a lot with the sleep problem until you can live without it. (i found elavil helpful, especially since one of the side-effects is sleepiness, heh.) and the previous poster could be right--your often-angry partner might very well be the cause--at the very least, it's probably exacerbating the problem to a degree. Kick him in the pants! :d
