What should i do about this guy ?? Help?

[Detailed Vision]

I met this guy once and both of us felt instant attraction, after i met him i had to travel to another country, but we still talked on FB , we've talked for 4 months online after we met and we were both so into each other, we have the exact same taste in music and art and everything!
Last month he stopped talking to me all of a sudden or saying hi at all, and since i never really used to start convo with him ( he always the one who starts them) i didnt try to talk to him, one of our mutual friends told me that the guy started seeing a girl we know,,, but he didnt mention anything on FB about it or even let his photos with her appear on his timeline, so hes kinda hiding it, he knows that i might go back home any day, i've already told him that.
so I'm confused should i send him a msg, ask him how he's doing, or should i leave it until he talks to me again???

I don't wanna go back home and find him seeing someone else, and i really don't wanna lose him
and btw i might have trouble going back home right now, it might be for another two months..

I'm sorry, but it does not seem like he cares about you anymore. You just have to move on. Sorry

I accept your doubt. Please, don't be suspicious of a person until you have seen them commit something wrong. I'm not saying that the person (mutual friend) and him is spoiling your impression on him OR doesn't want you to drift away. Just be sure whether it's true or not. If it's true and he's not sharing and is behaving odd-ly then it means he's got someone else. As you mentioned that he reduced texting you on FB, either of the way he must be busy with his personal life or else he indeed got a girl for himself. If he got someone, then you're too late to confess your love for him but don't woorry be happy that he's talking to you as a friend.
