It's better to combine the chapters, since a lot of short parts can be annoying.
I thought it was a guy at first and that we would get an interesting development where someone is interested in Tsuyu and she has to reject them, but a classic misunderstanding jealousy is fine As well.
I don't mind combined chapters BUT I would really appreciate if there was a small mention in each chapter of which chapters were combined into it since the situation might change at some point and clarity helps.
Just slap a (this chapter was originally released in 3 separate parts and combined for this release) as a footnote on the first page or somewhere.
