What does this mean? (Boy behaviour)

Fuck buddy of about 5 months and I ended it a month ago because he told me to get a bf who makes me happy (I guess I had pretty obvious feelings because I always asked him about girls and that)
He's 23 and I'm 19 which I guess also plays a part - I study and he works full time 
This morning he sends me this
Does he miss me or genuinely just curious as to what I'm up to?
