Why did we have to breakup? Was there something we can do?

I just experienced a really hard breakup with my girlfriend.

we both love each other so much, we were thinking of getting engaged so we reached out families.

My family are very supportive but me and her family don’t have a good relation.
they don’t like me for some reason that I don’t know and my girlfriend doesn’t know as well.

I talked with them and met them a couple of times and they were kinda rude and in the end they rejected me.

I tried to talk with them again, but they rejected me again with some silly excuse, so we agreed to breakup as it’s not meant to be.

P. S We can’t get engaged or married without each party family approval
