Would you be upset

My boyfriend and I currently aren't living together, my son and I live on our own. My boyfriend cheated on me a couple months back and we have been trying to work things out. Today he last texted me back at 2pm and it is now 2am and I have not heard from him all day. Normally we talk, is it crazy of me to think he's cheating on me again? Ugh I knew this wouldn't work out just because of the simple fact I always think he's cheating on me.
