Personal opinion, internship period of first love. For him, this relationship is very new. After the novelty, he found that there would be many ups and downs in love. At first, your willfulness challenged his patience, and then his tolerance broke out, quarreling and breaking up, which is a common phenomenon between lovers. I think his understanding of love has deepened and he is a little tired inside.
That's what men do. Don't say goodbye when you forgive them. However, he thinks that you are not serious about this relationship, and the relationship can be broken up at will. I said that the feelings of breaking up are not long.
He is angry at heart, angry at your willfulness and some words that hurt him.
Besides, I don't think it's a good thing that you are older than her. In a few years, you won't be young. He is still a young man, and he doesn't like you more. Love is not guaranteed.
First love is an internship. There is nothing wrong with this sentence. The chance of success in first love is very low, so be prepared psychologically ~
