Pic from ex

Not sure what he is trying to say to me by sending me pictures of me I placed in his scrapbook... Not even sure how to respond

Is he missing me...?
Am I still on his mind...?
Why, I don't understand.

(though, I did just read a note he sent me around a month ago addressed to my mum and I, saying how much he admires our courage and the relationship we have together, but also the letter was filled with worry and fears after not hearing from me for a while...).
