The site's tagline is "real girls, imaginary relationships." The service allows you to select a girl from their stable and carry on a pretend relationship with her...
Just make up how you met and include any details about yourself that you want your new girlfriend to know. Within days you'll receive personalized love letters by mail, e-mails, photos, special gifts... even phone messages or online chat. Every Imaginary Girlfriend is unique.
I suppose you can have imaginary sex with your imaginary girlfriend too. Of course, that's not really different than many of the relationships I had in high school. But why? Why would someone use this service, you ask?
There are many reasons. Some guys are tired of being told by friends and family to get a girlfriend. Maybe you would like to make someone else jealous when they see how enamored your new girlfriend is by you. Perhaps you are wondering what it's like to have a long distance girlfriend?
These are all good reasons, and it really depends on your situation. Having an Imaginary Girlfriend can be a lot of fun. What guy (or girl) wouldn't enjoy being showered with personal love letters and affection of an Imaginary Girlfriend? Having an Imaginary Girlfriend can be a great confidence booster!
Apparently Imaginary Girlfriends require less care than Sea Monkeys:
No! You do not have to write back or acknowledge your Imaginary Girlfriend.
Note, this should not be attempted with real girlfriends. It is highly unadvisable! At any rate, I think the best part of the service just might be what happens at the end:
When the stated time period is over, you can break up with your Imaginary Girlfriend for any reason you wish. She will write you a final letter begging you to take her back.
Now that's comedy.
