Nah, they are both gorg (obvs him more so) they do look good together, this photo is nice because they look natural and relaxed. Normally they are obviously so wary of being snapped together, like the final day photos their body language is off, but in photos that look to be private they just look like any other long term couple that know each other inside out - trust me I'm sure me and my hub look like cousins or siblings half the time because we are just so used to each other, theirs no need for constant affection - but that doesn't mean there isn't affection, but it's not PDAs it's little kisses in the kitchen, laying on each other on the sofa, having bum sex
So what he's obviously cheated, or the relationship has been weird, but I don't actually think he's cheated this summer, and whatever it clearly works for them. Let them be.
just let us share, just once sash, we'll clean him up before we send him home.
