Just have to give up

I have tried my best to make my relationship work. He has gone away with his mum and brother for a week and it's only the first day and he didn't bother to contact me all day til I text him. Yeah no big deal, but our relationship has been in trouble lately and this was supposed to be a break to think about things and "find himself" whatever that means to a 28 ur old man with a career and kids already I'm not really sure bit I don't like the idea of a holiday without ur partner and family to start with but he let his mum plan this trio and he's grown. He just acted like he wanted a holiday, so apparently then he deserves one and away He goes. I don't agree with the whole thing bit I also didn't want to lose him and he's been depressed on and off forever so I'm like whatever u feel u want to do..... I don't get why he can't just be normal and text or call the kids for bedtime, like what parent would just bail and then no contact? He's pissed me right off when he could have just done the right thing by me and them by a simple call or text... all day and night.... he's an arse isn't he? I'm alone with 4 kids and a prolapse which is killing me slowly by the second. .... why me
