We chatted once and didn't talk about the breakup, mostly about school and stuff, and I said I was doing well, he said said he was very glad to hear it, and that he had missed talking to me. He sent me a picture a few days ago of a note I had left in one of his books that he found. I had written, "I love you." I asked him why he sent it and he said he didn't really know, he just sent it.
We were best friends. I know he was starting to struggle with anxiety again and has a lot of life changes going on, plus I was about to move an hour away so we were going to see each other a little less. I just don't understand. He's 20 and I'm 21, and I know in his heart he is a sweet, genuine, kind person. This all is so unlike him. It's only been three weeks. Can anyone explain his behavior, and tell me if I have any hope?
