I see questions as to why Perez is to blame for Alex leaving but if you had been watching the show it's obvious. Alex along with most of the other housemates were already on a short fuse because of the way Perez has been acting up, then the other day Perez started blowing kisses at Alex and staring at him. Alex eventually lost his cool and called him F****** which got him a warning from BB.
Tonight's episode showed Alex getting annoyed because Perez was hanging over the food being cooked but in an earlier episode it was mentioned that Perez has smelly breath so this may have had something to do with it.
If there is someone in a room that you don't like and they continually smirk at you and you can't get away from them it makes you stressed and Alex was very close to blowing up so leaving was the best option.
Unfortunately I can see this forum going the way of every BB from the last few years, ' let's support the idiot because they have been most entertaining and the show would have been dead without them' But in reality it's just that they have had most airtime and been talked about on forums for all the wrong reasons and by people who never actually saw what happened but jumped on the band wagon anyway. So we end up with a loud mouthed ex prostitute and an offensive Gary Busey et al.. rant over.. going back to playing Candy Crush.

Other day Perez was funny, but you could see what he was up to night, which wasn't funny, and I was sorry to see Alex leave. We're left with a girls' House of nightmares, which I don't find amusing!
