A few months ago, back in February, me and my stepdad had a fall out. It was over something really stupid. He just had a different way of going about emptying a warmer to me. He offered to empty mine for me and I said "But Mum said last time you did it that way, you broke it". He didn't like it. He got in my face and said "Don't try and get smart with me". I just walked away and then spent the rest of the night in tears texting my mum telling her that I was fed up. Somehow my stepdad saw the messages the next day and we talked about it, made up, that was that.
A few weeks ago, him and my sister fell out when she drunkenly forgot that he asked her not to drop her fag butts on the decking. The next night him, my brother, and my mum had a talk about how we were all going to live together if we weren't always going to see eye to eye, and he mentioned that I told my mum he had threatened to beat me up. I never said that. I've gone through the messages countless times and I've never once mentioned violence. Then my mum went telling my grandparents and family and friends that I said that and made me look like the bad person. I want to confront her over this but I'm not sure it's worth another fall out. What should I do?
