<human>: Give me the gist of the text in a nutshell

So there is this project we are going to have next semester and I asked him more than a week ago if he wants to do it with me. I got no answer. The next day I met him in person and he told me that he doesn't know yet, if he will take the course even.

A few days later I asked him again, telling him that I'd really like to know, because otherwise I'd need to look for another partner as the registration for the groups was today. Still no answer, even though I could see he read it (Facebook). 

So I asked him yesterday that I would really like to know now, because registration is tomorrow. He answered late in the night telling me that he doesn't know if he takes this course/project next semester, so he can't say, yet.

Then today I was looking at the registered groups for the project and I see him with another friend of us in a group..
I instantly told him that I am really disappointed and he can't act in such manner - I am now waiting for his response.
<bot>: Anyway, what should I do now? Is the friendship lost, or did I overreact in some way? I really don't know..
