>which I already contributed little to as I struggled to organize my thoughts, and was really mostly him venting and brainstorming

You're already admitting that you didn't communicate with him because you struggled to organize your thoughts. That is not good communication.

You're 22, I don't think you should be relying on your boyfriend to wake you you up for your interview, you should be able to do that yourself.

He's possibly busy at work? Let him go through his day, maybe make him dinner for when he comes home and then talk to him during it.
