Is it normal if you look like a star to someone but look like sh*t to others?

I feel like a star to my ex boy friend. He looks at me like this powerful girl and believes in me so much. But I don't look at him like that. Yeah he's a good guy and everything, but not to the point where I'm just head over heels for him like he is for me. But to my current bf, I look at him like my star, my love, my dream guy, my everything...while I FEEL like he looks at me like whatever. Kind of like how I looked at my ex. My ex would feel like he wasn't good enough for me, the same way I feel about my bf. I just feel like he thinks he can do better and thats how I felt when I was with my ex bf. I don't want to think of it that way too much because when I do, I just get so depressed and hopeless...like just how I am confident I won't get back with my ex is how I feel my bf feels about me. I have it in my head that he feels so confident there is someone else better out there for him. He hasn't left me but he can act really careless sometimes. Then I have a feeling that he has a thing for this one girl but HE doesn't feel like he's good enough for her. And who knows, maybe if they happen to date, she'll look at him like nothing while I looked at him like the whole world. What is this supposed to mean? Or what should I do in my case? where I don't feel good enough for him and I trace back to my ex-relationship and compare? Should I just not compare because its all in my head? and consider he hasn't left me so I should feel good about myself despite his carelessness sometimes? Then again, it's weird how it could be sucha coincidence and a cycle with how you look/feel about people individually. Everyone has a different pair of eyes and an individual heart.
