Belle and Maurice fell out, not just because he didn’t like Rumple, but because he tried to send Belle over the town line so that she would lose her memories. He knew exactly what he was doing, he wanted her to forget about loving Rumple, even if the cost was that she would lose her identity.
I don’t want Belle and Maurice to reunite just because Rumple is now out of town, because that implies that Rumple was standing in the way and actively stopping Belle from reuniting with her father, which he wasn’t. Maurice would have made Belle marry Gaston even though she didn’t love him. At no point did Maurice consider Belle’s feelings. Maurice and Belle may have been close before Rumple took her away because Belle had no independence of her own, she just did what her father wanted. Belle agreeing to go with Rumple was her first step of making her own decisions.
I can see Maurice thinking that, now Rumple is out of town, he may have a shot at reuniting with Belle. However Belle truly loves Rumple whilst Maurice really hates him. Maurice isn’t going to change his attitude to Rumple, especially as he considers him “a monster”. If Maurice can’t ever accept the fact that Belle loves Rumple and that he is a part of her life, then the chance of Belle and her father reuniting is unlikely.
