Oh my! Isn't it obvious that he loves you to pieces. I don't think you need reassurance from anyone of us here to tell you that he loves you, he really really does!
And you won't believe how many people who would trade places with you. For as long as I've been on this site, I've encountered numerous questions asking how to make my cat like me, love me, be with me, be more affectionate, show me that he loves me, etc.
You have it really easy! So, just love him back. There is nothing wrong with him at all.
However, you should also be very very careful because a cat who is too attached to his owner is also not a healthy thing. He could easily suffer separation anxiety and depression if being left alone. So, for the best interest of both you and your cat, try to have him engaged in something else. Get him a new solo toy and allow him to investigate and play with it. If you have a window, install a window perch so he can sit by the window and observe the world.
Have someone else feed him from time to time. And do not focus all your waking time on him alone. If he wants attention, give him some and walk away. You need to train him not to rely on you too much because as I've said, it's unhealthy.
When he paws at your door, don't let her in. It might be cruel to think of it but it's just to make sure he can do well being alone sometimes.
Anyway, I am glad you have such a nice cat and I hope that you will try to train her to be more independent!
