Confused :/

My ex bf recently just broke up with me because he said he was unhappy and felt a bit smothered. We were together for over a year and the past couple of days he has been sending me snapchats of silly things (like the weather) for example he sent me a snapchat of the snow and then wrote to me saying "just wanted to say be careful driving.. Anyways ill get out of ur hair". It just confuses me because he keeps writing to me and yet he is the one who broke up with me. 
I asked him earlier had he my coat in his car or house because i cant find it and its my favourite and he said he would look and then told me about this hospital appointment he had to have a look at his heart and he was nervous and that he didnt know if i wanted to know but he thought hed tell me. Im just confused right now because i know i miss him and i duno what to think. Any opinions?
