uncertain future

My future with my boyfriend is uncertain when it comes to marry, sometimes I feel like I’m wasting my time in this relationship with him, also since he needs move back to his country, and keep telling me his future is uncertain too.

I’m also being sacrificing my studies and major because I want a future beside him and I’m not even sure if I will have one beside him? Do you guys understand me? I know I’m being really stupid and I’m feeling so overwhelmed about it
