Angel, I know you say you don't want you boyfriend to think your depression is because of him, but if you are as close as you say, then chances are he has noticed something is wrong with you, and since you are not talking to him about it, the natural reaction would be for him to think that your problem is with him. I know it sounds exactly the opposite of what you might expect, but you are much better off telling him about your problems and assuring him that they are not due to him than you are keeping quiet and letting him guess what the problem is.

Depression does make you see things all messed up, so your feeling that he no longer loves you could easily be due to the depression. So for now, I would just try telling him the truth about your depression...any conversations about whether he loves you can wait until you are feeling a bit better.

*hugs*
