He is showing less attention over text, does it mean he's less interested?

Anonymous
A guy I've known for a while text me and asked if I was still interested in him( he had a girlfriend before ) and I said I was, we started talking a lot, he would text me every day, every morning, flirt a lot, and 2 weeks later it seems to be much less. He still texts me nearly every day, and flirts a little, but what happened, why did he stop doing it so much. did it become too time consuming or did he not want to seem desperate? or is his interested fading? how do I tell if it is?
