Why did he smile afterwards? EASY 10 points!!!!!?

STORY: Bf broke up with me not over something big but I think he was just frustrated with me. He just knew that I was confused whether I liked him as a friend or if I liked him romantically. That same day he heard a rumor made up by my cousin saying that I was going to cheat on him and that I didn't like him, which was not true. He also heard that my cousin said he was ugly and I should be with someone better. He told me he doesn't like being compared and he said it was over. He said forget that BS of you not wanting to break my heart, He said if you want to do it then just do it. He also said he has enough women behind him and that I can be with whoever boy I like. Told him wasnt like that twice but he kept insisting to just be with anyone. Stay in mind I'm not like that and he is my 1st bf ever. He also told me that all he si going to say is to take care of myself and watch out who I hang out with. He said this all calmly while nto looking at me. It didn't really hurt me to be honest and I gave him the hand and said friend then. It stood quiet for like 1 minutes and he was looking at his friends and I was like you can go to your friend if you like... he looked at me and smile and said he doesn't want to leave me alone. I kept insisting since he seemed like he wanted too. So weird because like a few days I went up to him and he want a peck kiss in the lips mabey he forgot we werent together
