I need advise

I am in a very strange situation. so i am currently living in TX working as a researcher. I met this German guy (We are dating, but I am not sure if we are in a relationship or not) through my french friend. I used to hang out with my french friend almos everynight and we became pretty close friend. but He was a visiting scholar from France , so he went back to his country about a month ago. But when he was here, his friends and co-workers made fun of us becuase He was always telling them he's going out movies, drinks with me. So people thought we were dating, but we were not ( not even close to dating I'd say). Anyways, two or three weeks before he went back to his country, he introduced me one of his co-worker (the german guy). and After he left TX me and the German guy have been going out almost everyday. Almost everyday 2-3 hours before I get off work, he's been asking me for movies or tea or just hanging out. but One day he came over to my place for dinner and movie. During the movie, we both fell asleep (since we both work a lot of hours, we were tired) and we got up around 1 0r 2 a.m and we begun to talk about a lot of different things. We kinda holding our hands together and suddenly he pulled my hand/arm to his chest and gave me a huge. (we usaully don't even touch each other, there was no physical contact before) and he said " I am very attractive to you, and I know you are leaving this town soon and I am leaving in about two months as well, so I was controlling myself not to get into this situation, but I like you" and then he asked me " can we at least just enjoy each other's company while we are together? I know it will be hurtful at the end, but I really want to be with you until we seperate" ..so.. you know- I kinda like him as well, so I decided to take him for a granted while I am in town. But as we spend time together everynight, I am getting like him more and more. but I realized how cold he is. He never asked me to be his girlfriend, but he said i am his girlfriend. lol;
but I am very confused. I can't tell if he likes me or not. I do understand the fact that He is working on his master thesis these days, so he's busy and tired, but he doesn't seem to try hard enough to spend some time with me. For example, I am planing on leaving within 2 weeks, but I could stay two more weeks if He asks me and let me stay in his place for 2 weeks (not to mention he's got 2 female roommates and he told me today , one of them were firlting with him before but he told her "NO he's not interesed in her", but he doesn't aks me to stay longer. So I asked him today " Do you want me to stay a couple more weeks so that we can be together a little bit longer?" and he said " don't you have to go back home and take some class ? or work? don't stay in town for extra just because of me. it won't make any difference if you stay in town 1-2 weeks longer or not. but if you want to stay, I guess we hang out more" ... I was like.. DAMN!
you know that's not what I expected to hear from him.. he's so cold.
Also one of his friends is coming over to the USA in mid- august to traver different states in the USA with him. so I asked him " will you come to my hometown and visit me ?" and he said " I might, but I have to ask my friend and see if he wants to go"... hmmm..wtf

we are working in same department, so we sometimes go out lunch together (with a couple of friends) and hardly no one knows we are dating.

there are some guys are trying to date me and asking me out, and soon or later they ask me " are you dating the german guy" (we all are on facebook, and I have a lot of picture with him, but our status on fb, we are still singles)

but I don't know what to say when guys ask me if I am dating him or not. becuase I feel like the german guy is not telling anyone. so I asked him about that, and he said " I don't mind that people know if we are dating or not. but I am not the type of guy who is get on a table and make an announcement saying we are dating. If people know, they know. I don't have to hide you. I have no problem with that".. that kinda confused me.. i mean if u dating someone and if you want no other guys come up to your girl and firlting with her, you should let people know that she's taken. am i wrong about this? even three days ago, we went out for a good bye party for one of our friends, and there was at least 2 guys bought me drinks, asked me out. but he didn't do anything. well, other girls firlting with him too.. argggg...

one more thing, I am asian. so I feel more insecure about being with him.. becuase he's too cute ! so.. it makes me wonder why he's with me. I am not sure at this point if he likes me or not.. what can I do?
