I'm sure he is no Chad..
Seriously...from what she seemed to say was that it's a new relationship...I know that's no excuse but she is very vulnerable and although she has been a bit tearful and needy..she hasn't deserved the ****e she has had from Paul, Jemma and trampy Trisha.
Chad has been there and supported her...and he just happens to be very cool and suave and very good looking. She hasn't looked for any sort of showmance...that wasn't her intention...but who wouldn't fall for Chads charms when no one else is there for you..
