I am an esfj, and my best friend is an intj. I have read that the esfj and intj is a duality couple, meaning it is the best relationship. However, sometimes I feel like I need my intj friend more than she needs me. Is this true? I feel like she doesn't care for me as much, because she doesnt share her emotions or ever shares how she feels about me. I always tell her how I feel, because I want her to know I appreciate our her and our friendship. She saves messages from me saying how much I appreciate her and she also saves silly little letters I write her, but sometimes I just don't feel like she really needs or wants me, and it can be hurtful.
