I still think it was shoddy writing and I'm glad fans have made their feelings known via social media, to have Danny and Maxine trying to calm fans it was intense and even got #Robron trending, Emmerdale's twitter must be clogged with complaints.
I think they were perhaps having Robert debating how far he could/should go to play along with Rebecca to get what he wants. Keeping it all a bit ambiguous. But why have him turn down HF & Rebecca weeks ago have him propose to Aaron all the glorious goodness of SSW, what has changed from his POV.

They need to reiterate Robert's feelings for Rebecca if is he using her or are there something more there because now they've blurred the lines.
Rebecca trying to integrate herself in with Diane & Doug was sickening she's acting like a love sick teenager following her crush all over the place, loved Diane's telling her what she thought of her & her family until she run to Robert and what followed.

To think Robert was prepared to die with Aaron & proved the strength of his love 'no one else comes close' where did being desperate to have HF suddenly come from 2015! I know he mentioned it when he said 'I've got a wedding to pay for' the week before SSW but

he even defied Aaron with his not staying away from her by allowing her to drink with her
in Aaron's home of all places! What happened to 'I just want to be myself now with you?' none of this adds up !
But sticking with this and hoping Emmerdale right there wrongs and explain the plot holes they just created. I felt we'd got past all this now, if they were going to go down this route they should of done this before the engagement not directly after and so undermining it.
