Advice please

I’m at a loss. My boyfriend of 2 1/2 years broke up with me seemingly out of the blue. He said I stress him out, even though there are many other things that stress him out as well, and that I was the easiest thing to cut off right now. He’s a football coach, teacher and working on his masters degree. We went a week with no real communication, he said the first day was the hardest of his life, imagining his life without me. But then, the last few days were great because he was doing whatever he wanted, drinking and hanging out with his friends. After he said it, he cried, hugged me, told me he loved me, so I’m confused. We were in the process of building a house together and living with his parents, so I know that wasn’t an ideal situation. I’m hoping giving him some space to clear his head by getting an apartment for myself will help. Am I crazy to think he’ll come back to me eventually?
