I don’t think he left you hanging. When you ask if he wants to see you, he said “probably not”, it means “no”, after that keep asking him about it results in him stopping responding. to you.

Generally speaking this dating experience has too many issues after only few months. Typically first 3 months should be happy exciting time. Not time to try to mane changes in them. Some issues eventually pop up and not that early on

Also if after only 3 months you already want someone to change how he does things, that’s pretty much a problem. I don’t think it’s a good idea to date men who are not a right fit and try to make them into right fit by trying to “get” them do something they don’t want to do. Much better time spend looking for “ready made” men, the ones that don’t need changing
