Boyfriend troubles!!

Am I in the wrong? My boyfriend told me that he didn't want to come on holiday with me & my family and told me to tell my mum, so I obviously did! And then he has a go at me saying that I didn't want him to come in the first place etc. I don't know how this is my fault, I just done what he asked me to do. Now he's stormed out and I'm at his house! The reason he said he "doesn't want to come on holiday" was because I was ganna get some weed and he didn't agree with it.
