imessage is green but normally is blue
my girlfriend has an iphone XS, i have a 7. normally our texts are blue because it´s imessage. but my texts weren´t going through so i sent it as a text message. now everything is green. i turned imessage off and then back on. then i turned sms off. i called support and they said it should be blue for me but it´s not. it´s freaking me out, what do i do??
