Thank you both for your thoughts. You have made me think about the much broader picture, rather than just what is happening right now.
We have sat down together and communicated better than we ever have before. I have realised so much about myself, and why these unseen triggers occur. I have promised to use our safeword if i get this feeling and to then take myself to an empty room, count to at least 60 and try to be aware of where or why my anger was triggered. Then I can go back to Sir and explain and he can re assure.
Also in our conversation Sir stated that he thought because of me flaring up at dominance, that I did not actually want it and there for He was not really trying or aiming to be that way. He has said He will gradually start to increase his dominance.
We spoke about so much, I have learnt so much about myself. I understand now what I am scared of and why. Sir understands a lot more too.
Thank you both, your thoughts have been so helpful
