how could I win my ex back

Anjolie • 💕Trying to find my way💕
So I dated this guy for 3 months and   then we broke up because he said I was being mean and everything. then after we break up I try to change myself and I asked if we could date again and he said no should I just move on I mean I really want him back I felt like I've tried hard enough to change to try and get him back.
