That's amazing you have insight into that. At times people do that and are not consciously aware of it. The fact that you are aware of it can help you to not get into it, if you don't want, and give some reason to walk away. Or else just be you in all the relationships as an alterative. I know sometimes I have not been accepted as me--their loss not mine, I say.
I did it too years ago. It wasn't a good thing to do because it was not me he was interested in so I tried to be who I was not. Chalk it up to another learning experience. I try to walk away from that. It's perfectly fine to be just who we are at all times.
