If you wish to have your ex boyfriend back into your life, in spite of his being ruthless towards you and having left you forlorn, then it is your noble and humble nature that will surely win his heart and he will come back to you in repentance. What you have to do is follow the underlying tips meticulously.
In the breakup situation, your ex boyfriend will expect that you would blame, curse and hate him. But instead of it, show that you care for him even though you are dumped by him. He will be surprised and begin to think of you positively. Your pure and deep love will certainly move his heart and even though he has found some another person, he will think only about you. Believe this thing that true love always prevails.
Be nostalgic for some moments and recall the moments when your boyfriend used to move around you like a butterfly around the flower. It is perhaps you ignored your looks and become old fashioned for that he might be avoiding you. So have some leisure time to dress up gorgeously and to make up angelically. Have some party time and mix with friends. Be interactive socially. Your new avatar will certainly appeal him and compel him to think about you again. Perhaps he may not openly adore you, but applause your new looks speaking to the friends. Try to perceive this thing from your friends. If he secretly loves you and denies admitting, then be sure that you have won half the battle.
Once you are sure that you have generated enough interest and your ex boyfriend is curious in regard of you, then invite him at some place. But don't go there as single. Be accompanied with a couple of friends and be face to face with him. This will ensure that you are not too intimate to him. As you get stronger vibes from your ex boyfriend, you could take the further step and talk to the things over.
