Thanks for asking this question Sophia. I have been asking myself that the last few days too. And thank you to those who responded.
My take on it is also that we have this style of communication because we want to avoid pain. Added to that is your life circumstances - like how you said you moved a lot Sophia. I love to meet new people and be social, however I never allow someone to get close to me, and if I start to let someone in I never follow through with the relationship. I keep it at arm's length by not responding.
I grew up with a mother who viewed depression as nonexsistent. She was and is very judgemental. For me, I believe this is why I am scared to have close relationships - afraid the other person will judge me and not lilke me in the end.
So I think like the old saying goes, "face your fears". Very hard, but we have to start somewhere.
