Don't worry, just don't do it again. I know how you feel. Once i got angry and didn't say "i love you too" to my boyfriend, until he said "babyy, say it back"... it made me feel bad. I know how you feel.
aww you guys will be okay. i wish my ex boyfriend even said goodnight to me. i would say "have a goodnight baby" and he would answer back "Yup I will, bye."
