He wants me back but I’m confused

He broke up with me on Thursday after not doing anything for Valentines. I didn’t need him to get me anything, I didn’t expect that of him, but not even a text. I didn’t think much of it but it did bother me.

Then he broke up with me, because he said he needed to focus on the military. I understood and didn’t fight with him. For the next three days I was so hurt and confused, but I moved on with everything. Then he texts me about how he wants me back. He says I’m his “everything” and he can’t stop thinking about me, I’ll admit that I do miss him so much, but for some reason I’m hesitant to take him back. He said he ended things because he was worried we’d never see each other again and he would become attached. I’m just confused on what to do. My mind knows I shouldn’t take him back but my heart definitely wants to. I’m not sure what to do.
