Okay, my boyfriend has his phone signature set like this.
JEM&MLAM!*(: (We're talking about getting married.)
Okay, we we're texting -- and all of a sudden I got a random message saying "How long did it take you to realize it was dead?; and his signature said *JEM&MLAS!(: which is way different from his previous one. So, I asked him about it and it took him forever to right back, like almost 10 minutes, and he said he didn't know what I was talking about, that he never sent that message.
I told him that phone signatures just don't change themselves, but he still said he didn't do anything and that he never wrote that message.
Should I believe him?
