iPhone 12 Pro max

So I received a text from my BF after immediately hanging up two mins to be exact. saying Hello! With an exclamation point It showed he read a text I sent him at 12:54 and immediately responded Hello! At 12:54.. he claims he never meant to send me a text nor was it meant for anyone else.. that he must of clicked something by mistake so my question is could he have typed an h or he and selected Hello! With the exclamation point On his keypad while in his pocket or is hello! With the explanation point even a word choice when typing he (i know it’s not on an iPhone 8 just comes up he he’ll and hello) no exclamation point? I know it does not sound like a big deal but it is if trying to lie must mean intended for someone else he mistaken for me???
