I think that if you had to hide your true feelings in a relationship, then you probably did not trust your partner completely. Why did you do that?

I don't want my partner to hide his true feelings from me. And I would not want to hide my feelings from him. It is important for me to know that if I share my problems and experiences, I will be supported.

Maybe that's why you didn't show your true feelings because you thought that your partner wouldn't care?
