Is it normal or am i going crazy???

Ok so basically, I have always had a dysfunctional family but moved away from them a few years ago. Lately I have tried to reconnect for the sake of my siblings who are considerably younger then myself. anyways thats the background, now on to the question. Growing up both my mother and step father were very abusive but the thing is they keep telling me the abuse didnt happen. When I know it did. Today I met my mother and one for her sisters in town and basically my mum asked if I thought for her as my mother. I replied that I didnt. we get along ok but no I don't feel a motherly bond with her. She didnt take this well and got my sister involved. they both ganged up on me saying I always do stuff like this and that someday I will wake up a realise im a lier. I told my aunt (the sister) politely that she should not be involved in this convo as it was between myself and my mother. she refused to let my mother and me discuss it alone. I got kinda annoyed and mentioned the fact that her husband had been a creepy pervert toward me. she went totally crazy. anyways in summary, they are calling me a two-face person who always lies. I don't lie. Im just trying to keep the peace in my family but not doing things to annoy people. am I crazy and are they right, I am a total liar??
