Dead serious. We were together a couple of years when we decided to give it a go and live together.
The funniest part was I had already gotten internet installed at her place under my name. So I had to call the ISP and explain the whole situation to some complete stranger. They sympathized with me and told me not to worry about paying anything on it since I literally never used it. The guy explained that it was actually a fairly regular occurrence.
I later found out from her sister that there was another guy on the line and she did not want him to know about me. So if we lived together that would blow her cover with the other guy.
