this sweater is owned by whom?

Okay, too much on the knitting already, I know, but this one's a little different. Last year I was working on a pretty nice sweater for JP,

but then I got sidetracked by the Knitting Olympics, and then I had a problem with the sleeve and got frustrated, and then I decided I'd put it aside for a while until I liked it again, and then I got dumped by JP (damn that sweater curse), and now I have the front and back of a sweater that would fit me, but I'm not sure if it would be wrong for me to finish it for myself. Any ideas? I'm not really sure that I'm a big enough person to finish it and give it to JP at this point. I'd like to be, so maybe that's what I should do, but I really don't feel like I have that much nice in me.

I know, it's not technically the sweater curse because I didn't finish it, but I wanted to link anyway.
