Most Helpful Guy
Depends on the situation that resulted in you guys breaking up. If it was due to something you did then you should reach out to him. If the breakup was due to something he did then he should reach out to you. But since you said his ego is too big then unfortunately you will have to reach out first and if he responds back to you then he still likes you. Hopefully that helps :)

He would put his ego aside if he truly wanted the girl back and he would tell her. If he isn't doing that then he doesn't still like you.
