This is where you lose me every time !
You, me and everyone else have absolutely no idea if Ed wants to be with Jade.
The only evidence we have is the 2 of them looking very happy together whilst visiting Jades family in Ballina and Eds in Noosa. Since then they have had individual work commitments and he been hanging in Adelaide with family and friends.
Jade and Ed originate from her obsession, Tully and Drew from deceit. I think it's a toss up who will last the distance
Tully and Drew were based on deceit??? (as opposed to Ed/Jade)
Ed blatantly said early on to a lot of people that he wasn't interested in Jade, he nominated her, etc...(which could be for a number of reasons...but he wasn't completely honest with his feelings)
Tully may have cheated on her GF at the time but it was pretty evident that they both were into each other since the beginning...I don't think they were too deceitful to each other about their feelings
It's not exactly a toss up IMO (I'd bet on Tully/Drew making it longer any day...but it's possible Jade/Ed could last or neither)
