Remember Faye nominated Aaron three times in the early weeks so it is hardly surprising that her mum seemed to like him initially and has now come out against him. The Palmers have not shown much consistency unlike Aaron who has been loyal to Faye from the start.
It's going to be an uphill struggle for their relationship now which is a pity because they do seem to gel so well. Faye's mother is being naturally protective but has handled this all wrong in publicly humiliating her daughter. No wonder Faye lacks confidence.
