I dint agree with hoel Dianne speaks to Dianne. I just find it discussing, but I find it hard to feel bad for her, she did move in extremely quickly and was happy posting cringey relationship pictures and acting up to the vlogs. She definitely saw $$$ and didn't think through what would happen if the relationship didn't work out.
I do however think Dianne is in love with Joe. She is the type of woman who falls in love after like a week and thinks every guy she is with is going to be the one. Joe who knows if he loves her, I think he loves the content he gets from her, he loves her body, he loves that she cooks for him, he loves that he can make himself feel superior to her. But don't know if he is in love.
I don't think a break-up is on the cards anytime soon though. Dianne's career is everything to her and now she is signed to Joe, she is going to everything she can to make the relationship work, so that she will keep getting new opportunities with Matgarvine. Also don't think Joe will break it off either, considering he has done everything to basically make Dianne dependent on him. If they aren't engaged by the new year, Joe is going to get her pregnant as soon as the Joe and Dianne tour ends, no way is he going to want her to do another season of Strictly without him.
