He’s not the first and won’t be the last

He is attending the university in our hometown, she is attending a university in another province, a good twelve hours away. He is now regretting not researching universities further, though the three he applied to offered him scholarships but they were still not close to her. During the week life isn’t so bad for him, he is kept busy with classes but the weekends are difficult, sadness creeps in like a flood. They Skype daily for hours but it isn’t enough. He talks to me about applying to the university she goes to (his sister is also there). I explain, changing universities just for a girl is not really a good idea. He gives me other reasons, like smaller classes (he hates being in a class of 500) and this university has less than 2500 students. He also says he will be in a French environment which will be better for his French language skills.

He is 18 years old, so really I can’t stop him from applying, I tell him he must get 80% in all his classes, and if they break up, he cannot switch universities for that reason. What would you do?
