Correct as the whole deal hinges on the fact that you don't date the daughter, but once mommy finds out you not dating her im sure she'll stop seeing MC or... just maybe continue ? At the moment she knows you not seeing Chloe but you still dating her to some extent.
That's the big question at the minute after the ending to part 4 and judging by those pictures it looks like it although not sure how it will work out in the long run.
