I need help

So, I thought I am am on good relations with my friend, but today it was good until it was very bad.

​

So we were in another city for fun and drinks just to go out, we did buy jackets for ourselves because we did feel cold, when we came back to our city I thought that I did lost my jacket so I was worried, he initially said where the jacket can be, but I was so worried that I still was sad about it, the he started to make fun out of me that I lost it, so I told him that I don’t like when I am sad and somebody make fun out of it, then he asked if I am sure it was like that and what he should do, because he don’t care anymore, so I said just show me more support when I am sad and we basically split and he say bye, like goodbye now I did find the jacket but I don’t have one of my very few friends anymore, what do you think about it? Keep it serious please
