Right Non EEA family member after EEA(wife) left Uk

[M SALAH]

I am Non-EEA and family member(Husband) of an EEA national.
I got my EEA family Permit CARD VALID until 2020.

I am married since NOVEMBER 2014, we are not living together since 4 months, my wife has left the UK and went to poland with my son who was born in London 2 years ago, she has calmed a divorce from Poland and our marriage might end anytime soon. My wife worked in the UK from May 2015 to march 2017.

I am worried now after she left UK will I have any problem?
what should I do to save my stay in the UK.
Also, I would like to know am I entitled to apply for retained right of residence now?


Thank You.
