HI Rottz! Just wanted to check out your scene. I agree w/not asking these types of questions. For some reason, you just end up feeling worse. I know you are looking for some affirmation, but it seems like he needs to do it on his own time and his alien mind is just not full of the words that you want to hear.
I think you are also looking for something to work with though, like, what did she do differently? But, you do have some ammo! If you CAN do the 180-act hard to get, act somewhat disinterested. I know that you are very interested, but it seems to give him a charge. He needs to hunt it seems...So, give him a good chase. Act nonchalant, carefree...
