Why would he do that?

Well we were very much into each other but our relationship dynamics changed 3 weeks back. We only exchange texts once in a week or so. Last night around 1 am I got a text from him but I was not able to reply as I was asleep. Conveyed him that on text to which he replied "it's fine" in the morning. Now, I just got 2 pics from him via text. Those pics are not obsence or something like that. They are just plain and simple where he is taking a seminar at his new job.

Why would he send me those pics when we have not been talking properly for 3 weeks?
