I told him I don't want to be together but I do!

Helen asks :

There is a guy I have been kind of together for over a year now. When he lived in my country, we met up almost every day, had loads of fun together, even ended up in bed on our second date. Once when we were returning home from a party after having a little row, he asked what's going on between us and i stupidly said that we're just having fun until he leaves, he said that's stupid but i had a bit too much to drink and fell asleep. The topic never came up. But everything continued the same way, I went to visit him in his country, we went hiking, attended his work events together, I met all of his friends including his parents with whom we had dinner with! He has visited me, met my parents, my friends, came with me to my work events, etc. Everything is perfect, except I am in love with him and I want to be in a relationship with him, but I am too scared to ask him, I am quite sure he messes around with other women, that's how men are, right? He has a picture of us on his Facebook page, no sight of other women, but I just know.. He even made a Facebook account for the teddybear he gave me for my birthday and acts like it's a real kid, it's our own inside joke. But every time I try to write something nice to him, like I miss you, he just gets all awkward and doesn't reply, when i create the opportunity for him to be nice and caring towards me, he is teasingly mean, he doesn't give me random presents like guys who like a girl do. His words and actions just aren't the same. He will study in my country starting this fall, so maybe things develop further then? Please tell me I have not been wasting my time on him! I really-really don't know what he wants from me! And men say that women are impossible to understand.. Please give me some advice!
