Two things happen as guys go through more and more relationships:
(1) They gradually become less and less interested in relationships and lose those "lovey" feelings.
(2) They get smarter as to how to "play the game" of winning over women.
My guess is (2). He removed these pictures because he knows they will get in the way of him finding his next girlfriend. If I broke up with my girlfriend, the first thing I'd be doing is removing all our pictures simply because that would limit my chances of finding my next girlfriend.
Seriously though, who cares. You are putting too much thought into this.

Who broke up you or your bf? Maybe the break up was more hurtful then the last one...
