Hey Darling you can't make your mind think and your heart believe whatever you want to do in your life. Just try to accept and get used to his absence, and try to do something fun, enjoyable that will make you be intersted in your life without anyone else in it, and you begin to forget him. Don't try to date other person just for the sake of forgetting your ex. There'll be a time you will get a man that truely belongs to u. Trust the process, and stay strong😊
