I certainly agree with most of the things you said. I’ve been trying really hard to make a close relationship with my step-mom but unfortunately it never works. She told my sister that she’s not comfortable talking to me. I wonder why! I mean, I used to start conversation about all sort of things but all she used to do is nod or say one-word-answers (Yes, No). Then I stopped trying. I mean, I used to feel awkward when I didn’t use to get a response. We come home together mostly in car where we both are alone but we never talk. It’s always me taking the initiative. Her response is ‘Yes or No’. I feel really bad when she never replies. Makes it so much clear that she rather not talk about anything with me.
