Boyfriend Problems

So my boyfriend of almost half a year has been moody since yesterday over text , I hate arguing and try resolving things. It’s been happening ever so often , but I understand couples do that. I text him today with a good attitude and mood and he texts back “idk and idc” and I ask him if he’s mad at me and leaves me on open. I’m fuming rn and idk what to do. Am i doing wrong or should I say something?
