So, did she keep dating Stu?

I guess but your guess is as good as mime if not better then mine

In the last 15 minutes of the movie, Miranda's rekindled fondness of Daniel coincided with the absence of Stu. I think the family got back together and Stu went on his way.

I like to think Stu and Miranda stayed together. They were a nice fit I suppose, even if she was a psycho hose beast.

I'm sure she did, at least for a while. The ending scene where Daniel (as Mrs. Doubtfire) is answering the letter on the air about divorce was the movie's way of mading it clear that he and Miranda were done.

No reason Miranda and Stu wouldn't stay together, even if his name was more of a thick soup than a name..

I think so.. he fit her a ton more than Daniel did. She's a no-nonsense straight up lady, and so was he. You could see how much he cared for her once they first met again, he took the time to talk to her about things off the bat and was cool to her and the kids. He was a bit overly awful about Daniel and a bit arrogant overall but I think in time he woulda gotten over it and got along well with him.. hell he saved his life pretty much so he owed him that.

I always heard in the lost sequel they married and were gonna have another kid.. makes sense.

Daniel deserved someone more artistic, open minded, and with a clear soul. She had the latter (hidden but she had one,) she just didn't have enough of a POV to support Daniel and was a completely different wired person for him. She fit Stu a lot better.

I think the whole dinner would have freaked him out too much. Between almost dying at the table, and Daniel admitting to it. Then finding out that the house keeper whose been constantly busting your balls was actually her ex-husband. That would be more than most men would be able to handle. Especially a long time playboy like Stu who had only recently decided to settle down and embrace a woman with kids.

He seemed like a good guy and probably tried to keep it going, but ultimately he would recognize that he couldn't get over what happened. Within a month he would have already been on top of at least one 20 year old model.

Mrs. Doubtfire's speech at the end I think made it clear Daniel and Miranda didn't get back together, but each recognized that the other loved the kids and would only do what was best for them and it was better for them to have both their parents in their lives.

I assume that they continued dating but that isn't mentioned at all. In my opinion while they did, Miranda and her family (proably even Stu) might never have returned to Bridges (Restaurant) again because it would have brought up bad memories but be that as it may, I think later on Daniel must have apologized to Stu (for insulting him as Mrs Doubtfire) and approved of him as a potential new father for the kids while he could still see them, much like it is the case with some families depending on circumstances; kids have the pleasure of both their father and stepfather at times as long as both sides approve of each other
