I know this isnt a rave thread and I'll probably get shot down for saying this here but why does Gemma get more stick than Gorka?
In the example of him waking the kids up before leaving at 6...that is a huge inconvenience and I think it's entirely reasonable for her to be pissed off. And also good on her not to give in to Mia's request for TV time (notice she didn't ask to cuddle with her papa or anything along those lines). He's away for months on end and literally tells the world he hasn't seen the kids never mind her...as far as I can see that choice is his to make, Gemma rolls with it, gets her routine sorted (whether you think it's wrong or right it's needed to some degree!) then he pops in for the weekend, does whatever he wants then disappears again - let's be honest the kids will now be tired, grouchy, won't eat etc etc because of that.
He is in the wrong here. If he wants to be away for big periods like he is I personally think she's well within her rights to expect him to respect her & the kids routines or even how she runs the house (of course like most men he doesn't, does what he wants then to top it off she gets berated for it!)
