I think Alex has probably disgusted a lot of folks with his behaviour, which may cause him a problem in his quest for a tv career, as he may not be in there long enough to redeem himself and get the public back on side.
He should have left ages ago when he was popular. The moment he started messing with Alexandra's feelings ie going cold on her when Laura 2 went in, it all started to go down hill for him, and then he just went on to make it worse. He still is with all the "I really tried" nonsense.
I think he'd get more respect if he either was just honest, and said yeah I shouldn't have got back with her, my heart wasn't in it, or didn't bullshit so much about how hard he was trying,
