A break or a break up?

Hi. I am a girl in my early 30s, and have been seeing a guy in his early 30s for about 6 months now. We’ve both met friends, talked about future light plans, made mentions of meeting family, he’s referred to me as his girl, has posted my name on social media, etc. Things have been going overall well but it’s been a busy summer and we haven’t had a lot of time to connect and be together. The past month I noticed a shift in his level of communication and ultimately last week he told me he needed some time, hasn’t been feeling like himself and wanted to put a pause on things so he can figure his shit out. This obviously hurt me but I told him I wanted him to do what’s best for him and take the time he needs, and that I wouldn’t be reaching out/it would have to come from him. He said of course he would talk to me, said he wanted to make it clear that he didn’t want to end things fully and his feelings hadn’t changed for me at all.

Thoughts? Is he just freaking out thinking about the commitment? Or is he trying to let me down easy? I told him he could be honest with me if I did something wrong or if there was a reason and he said over and over there wasn’t, and that it was just him.
