Feeling Stuck Between Heart and Reality

There’s a girl I’ve known for almost a year now. We’re really close and there’s a strong connection between us. She’s 4.5 years older than me, and that’s the only thing holding us back from thinking seriously about marriage. I feel extremely comfortable with her — like I can be myself completely. The bond keeps getting stronger day by day, and I genuinely like her. But when I think about taking this to our parents, I hesitate because of the age factor. It makes me question whether I might regret something in the future if I choose marriage, or if I’ll regret losing someone who makes me feel this safe and supported. These thoughts keep circling in my head, and I’m unable to get clarity. I just wanted to share what I’m feeling and hear from people who’ve been through similar situations — how did you handle it?
