Feeling confused and heartbroken

I was in a relationship with him for around a year and we were seeing eachother quiet often he was caring alot and doing everything and out of sudden he stopped asking to see eachother or keep saying he has lot to do or that he os going directly to his house whenever i wanted to see him like in last two weeks we just saw eachother once as i asked.. 2 days ago i tried to tell him that im not happy with this situation and u can see his answer in the picture.. the day after i tried to call him at night which got auto rejected 2 times and that when i sent last messages.. am i over reacted?
