I just want to be seen, to be heard, to be acknowledged.

Hello everyone. I feel so alone in my relationship with my boyfriend of 6 years. I feel like I would do anything for him but he's not the same way. Every time I try to walk away from him he'll do something for me and I feel guilty so I end up staying. I want to feel like he's on my team but I just don't think he's like that. We used to have deep conversations so many years ago. Back when we were falling in love. He was my first love and I feel grateful to have experienced so many of life's "first" with him. But he's not the same person anymore. He looks right through me and doesn't even say hi to me when I come home from work. He doesn't ask about my day, my weekend, what I want to do and how I'm feeling. How I'm doing. Why I've been distant. He doesn't ask me anything anymore. I feel like I'm nothing to him. I feel like I'm just a person taking up space in his house. I feel so alone and unwanted. I'm so tired of begging him for answers. He calls me paranoid and insecure and tells me that everything is fine. It's so frustrating. I know everyone is different with their relationships. I just want to feel like I'm important to him. Why do I feel so alone?
