My heart has been broken too times by the same guy.
What do you think will happen if you get back with this guy again?
He will break my heart again.
Seems like you know your answer so if the guy asks you to get back together you should not give him another chance. Otherwise, as you said, you will just get your heart broken again. You really should have learnt from your mistake the last time.
Yeah, but I really like him.
I understand you must have strong feelings for him but you're letting yourself be hurt again and again. He has broken your heart every time you've dated him. You have to learn from this and not get back into a relationship with him.
