Trying to Figure Out How to Live My Life At This Stage

Every day seems to be a struggle for me. I feel at such loose ends being retired and lonely. I have never been a friend sort of person and since I don't drive it is hard to get anywhere so I am alone. Yes I have a significant other but am beginning to wonder exactly how significant we are to each other. He seems to either not understand how I feel or is just hoping it all goes away. This makes me both sad and angry. I try to get him to tell me his thoughts but that doesn't happen. I am not saying he doesn't want me to be happy but it seems like he is fine with the state of our relationship. When you are feeling like life is a hot mess and no one seems to notice it is very lonely. At least when I was working I had some sort of purpose. Now I feel like a small blip on the radar screen of life that goes unnoticed while it is there so is not noticed if it is gone.
