you let him be do not fight for him
He is saying that he likes you but he also likes someone else.
He likes someone else. You need to move on and forget it. He's not interested. If he breaks up with someone as good as you there must be something wrong with him. He may be mental
He is telling you that he likes another girl.
If a girl breaks up with you it's either she no longer feels ready (depends on how long you've been going out) or she prefers someone else to you or she thinks you're cheating on her.
He really likes someone else, and just didn't want to hurt you.
you can't if he likes someone else
it is always better to have a relationship with your parents be4 someone else ypur parents are the people you can look up to when he/she breaks your heart :DDD
Maybe he is having bad relationships with his Parents or family, or maybe hes over you and likes someone else.
Leave him alone and back off. He likes someone else.
When he has a penis.
Have someone else do it for you.
IMPROVED ANSWER:If someone tells you, "I really like you, but, my heart belongs to another." Your reply needs to be, "If you'd like to be friends, that is all we can be, and nothing more than that."If you wish you can tell them, "I thank you for your comment, but, I'm not interested if you belong to someone else."
