Is this normal email protocol between work colleagues?

i feel for you, but i don't think this is a big deal. maybe her phone was more convenient at the time (i get emails to my phone and when i respond i sometimes text...i don't have a hidden agenda when i do this). we don't know all the extenuating cirstances, so i'd just let it go and move on with my life. i'd try to keep in touch with some co-workers via email, but if it doesn't last, it doesn't last.
