It can't be someone pretending to be Rumple because Hyde controlled him with the dagger. The dagger wouldn't have worked with a fake Rumple.

Also a fake Rumple wouldn't have memories about her deals with the Evil Queen, which he clearly remembered. He also remembered about the coin from Papa Charming.

It's just Rumple being Rumple

Remember when the Beast mistreated Belle at the  beginning of Beauty and the Beast?

Well, it's the same thing here but it has lasted for 5 years now.

I'm pretty sure Rumple will make the ultimate sacrifice for Belle near to the series finale, and she will forgive him again and then the true love kiss and that's it.
