It's kind of a sad set up though isn't it? That people think they will be engaged by the end of the year but also that Dianne will be willing to exchange Joe for a brand new strictly toy and that Joe is gonna watch her like a hawk. Really, what kind of relationship is that?
I don't think Dianne is that fickle, this is just my opinion and everyone is free to disagree. I don't think Dianne broke up with the guy from Emmerdale because Joe was richer. I think their relationship was rocky at the best of times. They had already broken up by Valentines day last year and only got back together in May/June.
From her Instagram & twitter and that it looks like Dianne had a number of long distance relationships & i think Dianne is the type off girl who wants a more stable relationship, shes very close to her family, so I think she wants a guy who she can spend time with, who she can go home to every night. She hasn't had that in a number of years.
But I think Joe will keep sla very close watch on her, not because he thinks she will cheat, but because he's insecure and she's the first proper live in relationship he's had. From his videos I get the impression he doesn't like other guys anywhere near Dianne. Like she seems to be friends with Caspar and they double dated with Oli, but none of the buttercream are ever in the house when Dianne there. And even when Josh was doing his prank, if you watch Joe he doesn't take his eyes off Dianne for a second, it's the same around Alfie he kept very close to Dianne in Brighton.
My opinion is that Dianne is genuine about Joe and it won't be the Strictly curse as in her cheating on him that will break them up. It wi be Joe's jealousy that will put a strain on the relationship.
