Simma down now, y'all.
PEOPLE are fickle.
OP: You were only seeing each other for a month and in that month you had some problems. People who have a good sense of self respect won't stick around for more "problems" because when they do and they ignore red flags it's much harder to leave someone when they become a habit.
During the first month there shouldn't be many problems, not even a few. It's the beginning of the honeymoon period when you THINK you're compatible in every way (but you're usually not) and problems shouldn't exist.
Thank your lucky stars you've found out early that he is not a good match for you. The line about "starting fall in love with you so he distanced himself" is really telling you that hes not ready to be in a relationship WITH YOU. If he contacts you again it will likely be for booty only so don't fall into bed with him until you know what his intentions are.
“The willingness to accept responsibility for one’s own life is the source from which self-respect springs.” ~Joan Didion
