I think he's not being loyal towards his own girlfriend if he doesn't leave chantelle alne for one minute. It's a bit unfair and I'd not want to watch the show If I was Preston's girlfriend (not that I'd wanna be!!).. hmm its a tough one to call, maybe they're just friends but it does seem a bit intense after only about a fortnight. They will say they are the only youths in the house but still, they can also be friends with the older and wiser but they seem to be spending alot of time together on their own so it does make me wonder.... Hope that gives you and idea Glittereyes on what I think
