What should I do?

Hi guys,
I am sure that a lot of people ask about what they should do and I guess that no one is in the position to tell them what to do, but I just want your guys opinion on how I should react to the following situation:

I (21 year old female) have been friends with a guy (23) for about 2 months, we're both on exchange in a foreign country, but are both from Europe. We have become really good friends and we do almost everything together. Up to here, all good! Now, the other day it was his birthday and even though I was unable to spend it with him, I did get him a present: a Blender (it might seem stupid, but that's what he wanted, and since the price between a bottle of Vodka and a blender is almost none, I went for it). On the day that he came to pick it up at my place, besides from the fact that he brought me a chocolate (I think because he didn't want to come empty handed because he knew I had a gift for him), we hugged for the first time (3 times actually). It was him who initiated them. Now, ever since that day, we seem to be falling out. We don't talk as much as we used to, we only see each other in class and when I talk to him on FB, he doesn't seem to want to engage in conversation with me.

I could understand if it were I that had started the hugging and he could think that I am into him as more than just a friend, but it wasn't. I have tried to always be nice to him.

What would you guys do? Just wait for him to come round, ask him what is going on, just continue talking to him as if nothing is wrong...?

Thanks for any ideas. And please don't be mean! I just want things to go back to how they were, he was the person I was getting best along with...

Hmmm. I think I'd give him an open invitation, and if he didn't respond or was flakey about it, I'd leave it up to him to respond or invite you to hang out.

As you bought him the blender and were thinking in general of alcohol as well, perhaps send him a Facebook message of something like "Being that you have that nice new blender, I found a nice recipe for [sangria/some other alcoholic drink that involves blending things] that we could use to break it in. Interested?"

That is actually a really good idea! Thank you so much. I'll try that out and see how he reacts...

So I tried to invite him to my house party, he came over before the party, but left before it started...
We ended up deciding going on vacation together for a weekend, but he still acts really weird with me. He's annoying me -.- But he's a cool dude. Hate this!

You are both young...he's probably just nervous and afraid of the whole relationship thing...maybe he has never been in a serious relationship before. Be patient with him and give him a little space.

It could be that he likes you but is too nervous about it. It's possible. See you the weekend vacation goes and get back to us.
