Feeling lost after confessing my feelings for fwb

A few days ago I finally confessed to my fwb that I developped feelings for him. I went to his place, we ate in his bed and started cuddling. As I had decided to tell him, I felt super uncomfortable the whole time. He could defenetly sense it and seemed annoyed with me. Then I told him and he didn't expect me telling him. He said he did think we should talk about it so he was glad I told him, then said he wasn't ready for 'that' (I think he means feelings or a relationship, idk). He said he has trouble understanding his feelings so he doesn't know how he feels. I told him he would know if he feels it and he agreed. So we decided its best to stay friends. He looked confused and annoyed about the situation. I still slept at his place but we didn't touch. So then the next day, he texts me that it's not just black and white for him. He said he would rather give it a color than promise something. I have exams and really didn't know how to react, so I told him that I don't know what to say and want to focus on exams. The next day when texting he also said he is thinking a lot about the conversation, so I told him if he wants to talk about it some time he can, which he agreed to. So I went, and another friend of him was there. And I felt awkward the whole time and it felt like he was a little annoyed with me.

Anyways, I felt very uncomfortable and was hoping for us two to be alone to be able to talk more about the things he told me on text. And also it was very painful to hug goodbye and sleep at my own place instead of sleeping with him.

So today I was so confused and stressed about everything that I told him it's better to give me space and stop texting for a while to get over him, so we can stay friends. And he responded that I have to do what I think I have to do and that I already know he wants to stay friends. (seemed annoyed again).

I am so confused. Because I can't stop myself from believing he does have some feelings and if he would talk with me about them we can figure something out. But I really can't ask him if he wants to come over and talk about them, because I don't want to scare him off because he knows I have feelings. I keep dreaming about him having feelings for me. But I also feel like he doesn't like me enough. I feel like he is annoyed because I don't understand him and didn't give him the chance to explain himself. I am annoyed because of his very mixed signals. I really don't know what to do, but I should probably not text him because I told him it's better to stop texting ....
