We are on break but we still talk to one another as a couple, with a slight twist?

Has this happened to anyone else?.. My and my boyfriend have been going through rough times and we decided to take a break for a bit just to get our heads on straight and actually see what we are dealing with. We talk to each other as much as we did when we were together. But he won't talk to me on the phone. I don't know why, BUT_ when we text, he says lol and texts "haha" as if everything is okay. And then when I ask to call him, he denies me and says "uh idk..." and then he says "yeah, sorry" like is everything okay or not, you get me?... Advice on anything about this topic: being on a break. Thanks..
