Like others, I suggest you burn through it. Not because that is the best way or the only way, but, if you know usually have trouble finishing a project because you get stuck editing it, then definitely you should try to let the editing slide for now and just finish the story. There's a reason a lot of new writers get this advice (and writers who may not be new but have trouble finishing projects), and that's because, first and foremost, finishing the story if the most important thing. You can go back and edit now, but if you never have a finished draft, then what's the point? What does it matter how good it is if it's never done? Edits and revisions can always be done later. You may also find that things about the story improve as you write the rough draft - my characters often start off not very well rounded, but they get better as I go, and then I always go back and fix them in the early parts of the story.
I say this as someone who does, now, usually stop about a third of the way/halfway through the manuscript and go back to do some revising, and to revisit where the rest of the story is going to go. But I do that because I am confident I will finish, even if I take a break for some rewrites. I've finished plenty of projects and don't have the problem of getting bogged down in editing. I also discovered I HATE revision/second drafts - a lot of writers don't, because that's where they're story comes together. But that's not the way for me, I prefer to have the big stuff down in the first draft.
So, in conclusion, there's no one right way, but judging what you've said about your history, I would suggest just getting through it and going back to revise once it's done.
