i do this.
however, this was also an excuse i used to tell myself as i would emotionally withdraw. "i don't want to say anything hurtful, so i won't say anything at all."
i lacked the vocabulary and the emotional maturity to say:
"i am upset. i am hurt. please know that i love You, but give me space and time."
sometimes it's not the things we say, but the things we don't say.
