Permanent Resident card gets through British Citizen Sister

[Samedi]

Hi All,

Hope so I post to the correct place. I've been living here in the UK for more than 2 years, came from Hungary. I'm self-employed here, running my business. My sister has British citizenship. I plan to move back to Hungary in 6-12months, but I'm not sure at the moment I would like to come back to the UK or not(I would like to move back to Hungary due to relationship) in the future. I'm afraid if I shall leave the UK in 2019 and get back in 1 year for example (if something should goes wrong in relationship and would like to come back to the UK), I shall have difficulties, because I broke the 5 year route to settled status. (If I don't leave the country, I will get the settled status in summer 2021). I don't would like to leave the country without any kind of certain document.

The question is:
Can I get any kind of settled status or permanent resident card, or even British citizenship through my sister, as an extended family member?

Waiting for any answers.

No. British citizen in the UK can't sponsor family to the UK under the EEA/EU route and if you are over 18t then they cannot sponsor you either under the UK Immigration Rules.
