<human>: My boyfriend of 1 year is going to college next year, and so do I. He lives in another state, and we can only see each other in at least every 3 months. He began to make plans to earn money so we could buy an apartment and live together  in my city. I said that we are too young for that (or at least I am), but I would love to do that in the future, and nothing would make me happier. He got angry and sad, and then slept. Next day, he was acting normal, but I feel like he doesn't take our relatioship seriously anymore.  What should I do?

Could you distill the essence of the text into 1-3 sentences?
