I suggest you try to talk to him about the situation. This also depends if you have feelings or not. Ask him why he has suddenly gone cold because you miss the good bonding moments.If you don`t have feelings for this guy, it is best to inform him so that everything is cleared out. However, if you do have feelings for the guy, i think you should still inform him about it and see where it goes from there. There might be various reasons as to why he is ignoring you. The only solution for this is to have a talk with him. If you keep ignoring the issue, you might lose your friend. Hope this helps.
