No Response in 5 Seconds? Bye
This has to be one of the strangest exchanges we’ve seen in a long time. After not hearing from the guy for five entire minutes, she knew the relationship was over. During those five minutes, he probably planned a trip to Europe with another girl and proposed to her.
These people might have some history, but without knowing it, we can only assume that this woman has a pretty short fuse. Look, guy, don’t try to hold her back. Let her walk out of your life and be happy about it. If she can’t believe that he isn’t active on two messenger services at the same time, she won’t believe a lot of other things.
