What's a good way to respond to your boyfriend telling you that he's going out with his friends?

Boyfriend politely asked me to leave his house on a Sunday afternoon because he said he had homework to do. 6 hours after I left, he texted me saying he was going out with his friends. He usually is sweet and affectionate over texts but this time, he just said he was going out. He didn't send his usual "I miss you" text and wait 6 hours after I left for him to reach out. I'm thinking to text him "Have fun." Should I text back or just ignore him?
