Help 😔

I don't know what to do😒 my boyfriend and I have been fighting lately and I've started to realise that he turns everything back on me! It's always my fault and if I try and say what I think or the truth he said "fuck off and stop lying" 😒 I don't know what to do because when we fight in so unhappy but when we aren't fighting our relationship is perfect, what do I do😕
