Why my ex said "I tried to forget you that time"?

I had a talk with my ex boyfriend, he's my first love.. I just can't forget and move on.. I dated many guys but always broke up.. every time I'm broke up with guys, I always told him.. he's like my bestfriend.. last time I broke up with my ex fiance was in December, he cheated on me.. so my first love will move to my country for 2 years for his research (doctoral degree) i was like "oh okay cool" but after I broke up with my ex fiance I told him (first love) "I can't move on from you, I tried to be with someone else.. I don't know why and its so annoying.. how can I be with someone else if im still thinking about you?" So he told me "let's meet up again and make sure if our feelings still there, you know what? I deleted your pictures, I tried to forget you" what does it mean?
