I think mama g living with them is actually good for the marriage
with how lazy elle is, I don’t think she can cope with newborn duties, which would then typically fall on daddy, and I doubt Fisherman would rise to the occasion and take on night feeds/diaper duty etc. i think he would be more than happy to dump baby duties on Ginette. PLUS imagine how difficult it would be to deal with Elle alone. With Ginette around there’s someone to take the brunt of the work & pander to Elles ridiculous comments.
