Why do you think it is weird? Emotions don't just disapear, especially not love.
Now obviously I can't tell you what to do, but I can share one of my observations with you: Being "just friends" with someone you are in love with doesn't work. Now I am speaking without any personal experience here, so take it with a grain of salt, these are merely things I have observed in others: When people are in love, but do not act on it for one reason or another, a lot of tension is build up. Everything is overthought. This tension undermines the entire relationship, and you end up either going crazy, avoiding him or confessing everything.
If he still loves you, and you still love him, and you get on "really well"... then what is holding you back? You might wanna consider why you are so confused about this.
Hope I have been of a little help, and that I haven't confused you further.

Strange how that worked out isn't it?
