This is all great advice, the trick I've found has been keeping it going, finding the right balance between openess and aloofness.
Things with my W were progressing nicely and then they started to slow a little. I paniced and persued because that's what I do. And, predictably, things slowed further. Then I went away for my brothers wedding last weekend, didn't talk to her for 3 days (she's used to me calling almost nightly), and sent her many wedding pics, some of which included me dancing with the bridesmaids (I was the best man so I had to, right). Past couple of days, she's said she missed me, she loves me, she can't wait to see me; the slow down is gone.
All that to say, I think you've gotten some great advice here and need to pull back a little. Find the balance again, make yourself more challenging and when he comes back around, try to slow yourself down a little on your attachment to him. It's hard cause it's exactly what you want, that attachment, but I think what you're seeing now is the direct result of not going more slowly.
You do deserve to be loved. Believe it and he will too.
