Being in a relationship and spending the day together or even spending a few days together is different to living with someone 24/7 with no kind of distractions or even opportunity for a sustained break from each other. It's probably too much for most relationships to take.

Early on in the series Stevi was jealous when he thought he saw Chloe eyeing up James. Fast-forward a few days later and when BB announced they must give up showing affection to each other for the task, he positively beamed, before realising what a commotion she was making over it.

Then there's him suggesting a break from each other, shirking away from being cuddled by the storeroom and he also doesn't really seem to want to fight her corner that passionately when she's in hot water with someone else. He makes token gestures but he gives the impression of someone whose being married 45 years who just wants to get hit by a bus to finally end his misery.

I've never been convinced her heart has really truly been in it from the start. From her perspective it seems all too conveniently showy and I think she's far more clued-up than her ditsy persona suggests. But I really don't think he's in love with her either now.

I don't think he was ever in love with her nor she with him

They are fake.

Neither have ever loved the other, they are a reality tv scripted couple.

I am on the fence about whether they are a real couple or not.
I do think that Stevi is not as interested in Chloe like he was at the beginning, makes you wonder if Emma is right about them being on CBB to break up on tv.

It does appear she likes him more than he likes her she's very child like & needy

Even if he has - does anyone care - even the cringeworthy Chloe Jasmine ?
