Please help. How do i fix this Relationship?

Cor

Could you please give insight on a man. I have been talking to this Guy for a month he is really sweet and initiates everything (all conversation and hangouts). He is pretty consistent and would talk at least 6 times out of the week. But last weekend we hung out and he stayed the night and saw a message on my phone saying “good morning babe” he then called me a player and ignored my text and calls the remainder of the day. I reached out to him again after giving him a day break and he responded a few times but was very distant and has been distant. He then just started to ignore me. Then he got a new number and reached out letting me know he has a new number but he is still distant. Why would he give me his new number if he was still going to be mad. Do you think he is done with me and gonna cut me off or is there still a chance to fix it?
