He didn't have a "relationship" with her, unless you're thinking of the virtual reality thing he did, but yes, they knew about him spending time with her.

Lois.
I think it was when Lois became fat and her and peter had fat sex.
It's kind of complicated. I think he hates Brian because he loves Lois (look who's talking) and like ya know how could he do that to peter who brought him into his home blah blah blah
