Is my boyfriend ignoring me?

He got grounded for a month and got his phone back last night. He sent me a text and we sent about five texts before he sent me "I gotta go to sleep. I'll text you tomorrow! nite baby! I love u" In the morning I got a good morning text and we started to talk about the usual(talking about how we'vebeen and planning out or next date) wetexted for an hour then he sent me "lol brb i gotta go change :3" and I haven't heard from him since. Its been almost three hours. Its not like him and his friends the night before told me how he never shuts up about me. Is he ignoring? How do I get over his silent break up? help me please.
