After 7 dates and he is still seeing someone else? What should I do?

So I met this guy online and we have been texting and hanging out for one and half months. He’s leaving my country in two weeks (but he comes back sometimes). We’ve completed the 7th date. But it seems he’s still on the dating app and seeing some other girls. I feel quite upset but I don’t know if I should talk about it with him coz if that’s what he wants, that’s what he wants. But I just don’t like dating multiple people at the same time and I wish he could do the same. Am I asking too much?
