Do I have a chance? Capricorn men (in late 20's)?

so dated a cap man for the last 1.5 years and he broke up with me suddenly a month ago after telling me only an hour before that he loved me and didn't want to break up with me during a discussion we had that then turned into a mini argument. (we never argued until that point). he was still telling me he loved me after we broke up but communication has since become sparse in the last couple of weeks. he thinks were not 100% compatible but I know he is scared of the commitment and offering me what he thinks I need long term. now would a stubborn cap man realize and admit his mistake and try to make amends eventually or stick to his decision? he has tried moving on already and told me that he isn't ready for that yet. do I have a chance?
