To be honest, that is how i react when we are talking with my husband about our feelings toward each other in the beginning of our relationship and i am 31, we are married for 2 years, together for 7 and have a child. When you are crushing in love, you always act like that ( ̄∇ ̄")
Bro might be a school girl in love. He reacts the same way my lil sis when shes talking about what she did with her crush lmao
