Most Helpful Guy
Most Helpful Girl
He is hurting. He clearly didn't want your relationship to end but it did and then you wanted him to act as a friend when he still has feelings for you which is already a difficult position to be in. He probably hoped that there would be a chance that you two would get back together, but you said no and rejected his kiss etc. He probably realised then that he could not act in the way that you wanted him to. He cannot be just a friend when he wants more, it is just not possible nor fair on him to ask that of him. Why were you upset that he kissed another girl? You broke it off with him, and told him you didn't want anything with him, you have no right to be upset about him kissing or being with anyone else. He tried to be your friend as you wanted, but it is not possible for him to do so. He wants space and time to get over you properly which is what he needs and is normal after any break up. His feelings for you have to go away if any friendship is possible later down the line. You will have to respect that choice.
