Guy's Behavior

Why would he have cried after we didn’t see each other for almost half a year?

I had a mental breakdown at the beginning of this year due to consistent verbal abuse from my grandpa, and I will admit I was “crazy.” I had a super great guy in my life; but I pushed him away because I was embarrassed from my situation. I thought when I saw him again and I gave him the book, he would tell me to leave him alone.

Instead, he smiled said it was cool, gave me and then started crying.

Why would he have reacted this way when we were apart longer than we were together?
