How to make an ex-boyfriend angry?

I had an agreement with my ex-boyfriend at that time to call me around my birthday 12 to celebrate for me. However, he didn't call me on time at last, and I waited for a long time without hearing from him. I was very angry at that time and thought that he didn't cherish me and our relationship. In order to save this situation, he needs to make a sincere apology and promise to pay more attention to the influence of his actions on our relationship in the future.

2. Don't respect my opinion

Another time, we discussed some things together. He was too conceited to listen to my advice at first. I was angry and felt neglected. In order to remedy this situation, he needs to realize that my ideas are equally important and should respect my opinions. He needs to listen to my voice carefully and avoid being too self-righteous.

3. Don't value my feelings

He once hurt me in one thing, but he didn't want to admit his mistake or apologize. I feel very sad and disappointed, and I feel that he is indifferent to my feelings. In order to save this situation, he needs to realize that his behavior has affected me and apologize to me. Tell him that he recognizes the bad effects of this behavior and promises to be more responsible and respect my feelings in the future.
