Should I text him back? ?

After a small argument over the phone last night, I texted my boyfriend and somewhat apologized. I basically said, "Don't be mad at me." I waited, but he never responded. This morning he texted me back. I didn't respond because I thought, if yu really wanted to work things out you would've texted back last night. He's a sweet guy and I really like him and I think he still likes me. I don't think he can get over me that fast, but he's a charmer. A lot of girls want him and he can easily have any.
