Well, I see the difference, but here's my take: 1. "I start feeling like you don't matter to me" Okay, this is how I feel, I've lost the feeling of closeness that accompanies ML with her. 2. "I start feeling like I don't matter to you" Okay, I also feel this way, because I don't feel loved by her, I don't feel she cares enough to show me love in the way I have clearly articulated to her I want to be shown.
