Bringing back a guy who's in love with another girl isn't easy. In this case, there is no point in trying to compete with your appearance. Your task is not to draw his attention to yourself, using all sorts of tricks, but to remain yourself and show real feelings.
Who does he like?
If you want to return a guy who is in love with another girl, do not try to compete with her, this can make you very jealous, and she, in turn, will prevent you from acting right. Before you return the guy, find out who this girl is, do you really have a chance of success? Find out how serious the relationship is? Are they happy together? If you find that they love each other, think about whether to interfere with their relationship? If it turns out that they are just friends, you have a good chance of getting your boyfriend back.
Get to know your ex better
If your ex is dating another girl, you probably don't know everything about him, and he may not be getting what he expects from you. Try to be with him more often, for example, if you study in the same class, participate with him in common projects that are interesting to him, show interest in his endeavors in various matters. Find out what he likes to do in his free time, if you have common hobbies.
If you find out about your ex-boyfriend's new hobbies, such as sports or a hobby, try to research the issue. Show that you have similar interests and behave naturally. Don't stress that you are doing this on purpose.
Become a friend to him
Regardless of why you broke up, if you want your boyfriend back, you need to be a good friend to him. Do not under any circumstances discuss his current girlfriend with him, do not insult her or gossip. Your job is to impress him again.
Be honest with yourself when asked about your feelings for your ex. Do you really still love him or is it jealousy and it’s just hard for you to see him in the company of another girl. Do not be mistaken in your feelings, in the future they can lead to a new breakup.
Do not hurry
If you've become good friends, take the next step. Come to his company more often, attend various events with him (sports competition, cinema, etc.), hint him about a date. However, do not be too persistent and take your time, your suggestions should be friendly and innocent at first. If your ex-boyfriend's relationship with his current girlfriend is not too serious and you manage to win him over again, it will only be a matter of time before he returns to you.
