I lied to him

I went on holiday with a friend (female) that my bf does not like and didn't tell him until a few days before because I knew he would flip out anyway came back now he's cross because she came anyway got back and he is freaking out cos he said he does not trusts me with her I have never cheated on him yet he's implying that I am like her (she's kinda a hoe) how do I reason with him :(
