Am I misinterpreting our communication?

So I started dating this great guy after 2 years of him trying. We hit it off great--constant conversations, fun and happy dates, talking everyday for hours at a time or pretty consistent text conversation throughout the day. We went on vacation recently and I felt him getting distant physically. He finally opened up and told me that he's unsure if I've made peace with my past partners. We discuss it some and we go back to our normal lives.

He's not as communicative for the past week. Sporadic text. We were able to talk on phone for few hours altogether throughout the week, which was nice but slightly forced because of the awkwardness. I've asked him to either be consistent with communication as before or to just take a hike instead.

Granted, I know his job has its demands and me being unemployed gives me probably too much time on my hands. However, this has been the case for the past 1.5 months of us dating. I think we're both just frustrated. He's a more logical communicator so he lacks the emotions while I'm an emotional communicator and lack the logic. I also overthink with all of the anxiety.

He prefers and ask of me to be as direct as possible instead of sugarcoating.

I don't want to compromise my needs or add leniency just so that he can meet them again, although he was meeting them well before. I'm not sure what else to say or do. I feel bad because he asked me what he's doing wrong today, and I never want him to feel as if that's the case because he's a great guy that does sooo much. I never want him to feel like less because we're having a difficulty.

I'm just feeling alone and frustrated all of a sudden.

For disclosure, other pet peeves include:
-I'll give a whole speech on how I feel and why and his response is usually a word like, "okay"
-He isn't very vocal on expressing affection or affectionate things, but he'll gladly demonstrate it physically. Example, doesn't call me pet names or give compliments.
