Guess we will never know.. Unless if Chloe visit James and we can see the relation between them
From the VH Newsletter:
Chloe & James haven't yet settled their relations. We got info from them, that they will stay there up to the end of August, and will move to Misty's place for a couple of days. After that, James & Lisa will be moving to a separate larger apartment for them. Chloe will leave the project by then.
