Then why would hermione be with harry

Who else would she be with

Because once again, Rowling wanted it to be that way.

Who else would she be with

Anyone she wanted to be with I guess!

Rowling said during an interview that Ron -Hermione love was a great mistake that Hermione should have ended up with Harry, this was confirmed by Emma Watson and Rupert Grint: Harry and Hermione were meant for each other all along, instead Ron and Hermione were simply a bad match and Ron would have never been able to make her happy. So sorry about this because this means that if they were still together she maybe not be happy . ..

But I don't like her with harry either!!

Well look at the way it happened and live a little outside of the world of Harry Potter.

Ron and Hermione are still together in Cursed Child. If, according to you, she's maybe not happy with Ron, then she would have left him long ago, and not be with him after so many years.

Maybe you are right maybe not... Hermione is a loyal person, trustworthy, and since she got married to Ron and had children I hardly imagine she could leave him and mostly her children only because she was unhappy with him. And I can see Wizardy world is a bit old fashioned and this doesn't make things easier if you want to divorce.
