I am worried about my girlfriend and whether she has lost interest in me.

Lately, things have felt difficult. It seems like I'm receiving a cold shoulder at every turn, and the spark between us seems to have disappeared. She rarely wants to hug or touch me anymore and never takes the initiative. I can't shake the feeling that she's grown tired of me. To provide some context, I have a leg injury that often leaves me disabled, limiting my ability to do much physically. I believe this has contributed to the situation, but whenever I bring it up, I feel dismissed. I also struggled with addiction in the past and was generally a mess financially. I can't help but feel like I was just a project for her, and now that I've improved in many ways—except for my leg—I worry that our relationship may not endure much longer. I miss her deeply, both physically and emotionally, and I've expressed this to her. I don't feel loved, and I'm not the type to reciprocate affection if I don't sense it in return. The only times we tend to be intimate are after we argue or have lengthy discussions about our issues. Most of the time, though, she doesn't seem willing to communicate, often saying, "there's no point."
