I'm going to swim against the current (what the hell do I know???) and agree with Charlie. If you love him and you're itching to tell him so, do it. Just do it without expectations - and let him know that as well.
There's a novel by Vonnegut where one person says to another: "I love you."
The other replies: "When you say that, I feel like you're pointing a gun at my head. What else am I allowed to reply but 'I love you, too'?"
Make sure that J knows that there's no gun.
Q: Is it ever too soon? To say I love you?
A: Better too soon than too late. (just my opinion)
p.s. I think that you and Beodude123 should invite J to read these threads. (just a crazy idea)
