In fact, your situation is very similar to what I am facing now. I am also a senior three, but I am a girl. My school belongs to the north, my boyfriend is from the north, and I am from the south across the sea. The distance between us is far away, but I have actually thought about it many times whether I can make a positive result after graduation. I used to think that it would be good for two people to stick to it, but I have learned a lot when I grow up. There will be a lot of pressure in the future. Two people together are not only two people but also a home.
First of all, what the landlord should consider at this stage is whether you need to upgrade. I think no matter what the situation is, as long as you keep improving yourself, you will not regret it in the future. And I think it's too early to think about whether we will be together in the future, because you don't know which city you will go to after graduation, and you don't know whether two people will be together. Many situations that lead to the sudden breakup of two people, some work reasons and family reasons are unknown at present. You really don't need to think about how to break up now. I think it will only cause you trouble. Love actually accounts for 10% in your later life. There are many beautiful things in life, except love.
Secondly, if you think about it carefully, many things actually don't have a happy ending, and there are also many uncomfortable things in this world. I wonder if the landlord has heard of Schrodinger's Cat. In fact, we don't know whether the ending is good or bad until many things are over. But we can't say that we don't start or just want to stop for an unknown result.
The outcome of many things is not important, but the process. This love makes you happy and memorable. I don't feel any regret. Some people don't spend their whole lives together, but they seem to have spent their whole lives. Just leave no regrets.
Good wishes!
