When You are Celebrating Your Anniversary?

My fiance and i are celebrating our first year anniversary.

I bought him a dog tag and had it engraved, it was the only jewelry he could wear under his shirt. but i put his favourite picture of us on it, And a very nice loving inscription.

See, the thing is he never said happy anniversary on Facebook, twitter, or anything.

I wrote a blog about it, and i also tweeted it. i also wrote out over two hundred things i love about him on a Bristol board and gave it to him

I made his birthday Extra special, took him to his favourite restaurant, and bought him really sweet gifts.I wrote a giant happy birthday on Facebook, he just liked it, the only person he responded to for the birthday wishes was one of his friends cause it was an inside joke.

So i want to know, why does he never publicly acknowledge the things I've done for him? Or our anniversary or anything?

Thanks for Answering. Sorry it's long.

Cheers
