I’m confused

My girlfriend and I have been planning to move in together next year and because we live in different countries I would be moving to her country.

Today we were talking about it and she’s planning on going to university for 6 years and she won’t really have time for a good paying job to pay for rent which is understandable but it means she would love with her parents.

I’m so confused, I can’t pay for 6 years rent on my own when I’ve just moved to a different country, so what the hell do we do for 6 years if we can’t live together

Long distance is so hard but 6 years of it is tortures

I need advice, do we have to break up??
