How to stop playing iN his games?

He reply me back after 10 hours! Or the next day sometimes at night! And reply back with short answer! Now am doing the same but really I started to feel cold from the way he’s treating me...

It let me feel that am not that important to him... really am tired..

What should I do?

I don’t feel he’s putting effort! Lately I felt that am the one trying... but he became more careless when I invested more...
