Place holder?

Iast night i had a talk with my partner about the future, expectations , plans , goals etc . We’ve known each other for roughly 6 months. Anyways, i told him I might not be in it for the long run , i May want to move back to my country in maybe the next 10 years ( I’m Nigerian living in Norway, he’s Norwegian) , i certainly don’t want kids , he wants them. I told him I’m physically attracted to him but not emotionally. I basically said I’m not invested in a relationship because i have other priorities atm , school/ building a life for myself. he says he wants a serious relationship with commitment. After all this he still wants to be with me , i dont know why , i feel like I’m dragging him along in my uncertain future. I like this man but it doesn’t get deeper than that. Has someone been in a situation where they have been the one less invested? He’s 29, I’m 24.
