<human>: I'm 23F and my boyfriend is 23M and we've been together for five years. We live in the city where we went to uni but every so often we head back home. My boyfriend helps his dad out with work when he goes home. They also own a lot of horses and his sister is pursuing an equestrian career. He helps out at the stables as well as a favour to his sister who is 20.

Today was one example of how they blame everything on him. His sister asked him to clean out a stable for her while she went shopping (?!!) which he said he would do along with helping his dad. His dad told him not to do it, to wait until his sister got home to move the horse because he wanted to make sure the horse would be ok. My boyfriend would have been able to move it but he did as his dad asked. When his sister and mum came home from shopping they went ballistic because he didn't clean out the stable even though he explained his dad asked him to wait. His sister called him a w**ker and a child and when he said he was sick of her saying crap like that and then apologising later she started crying!! His mum defended his sister and his dad hasn't come home yet.

This is just one example of them blaming him for everything and constantly putting him down. His general reaction to this is to let it go because, as he puts it, he can't be bothered with the hassle of arguing. It just makes my blood boil because his sister is so spoiled and gets away with murder and he is the complete opposite. He'd do anything for anyone and they walk all over him. I wish I could say something to them but I don't know if it's my place.

They can be really nice people as well sometimes but he gets this treatment at least once a week. Am I over reacting? Is this normal? My parents gave me a hard time when I was growing up too but it was when I deserved it!! Your thoughts??

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Boyfriend's family are constantly running him down and blaming him for stuff that goes wrong. How do we deal with it?
