Husband applying PR then what about my EEA PR(EEA4) route?

[Hevenly]

Hello,
My husband is a european citizen and working in UK since 2013. I got EEA2 in 2014.
After Brexit issue, we have been considering that he may needs to apply PR card just in case. EEA members can apply british PR visa after living 5 years fully in UK as we know.
so he is going to apply PR visa ( I am not sure if the PR visa for EU citizen is called EEA3.) in three months, then I am wondering if it affects to my EEA family visa route as well when the time comes for applying EEA PR(EEA4) in 2019. if so, we will delay him to apply his PR visa.
I am a bit afraid of being confused^^:,
Is there anyone who can advice of this?
Thanks.
