Don't let them fool you

I've received emails and calls from girls i haven't seen for a year.

Be kind and inform her that you do/don't care for this sort of behavior.

I've given a green light to a few. I don't mind texts/calls from those few. I haven't ANYONE to hide it from; yet. LOL

While providers should not sent messages to those who've not requested to recieve them, you can not guarentee that it won't happen.  This is why you should use a separate e-mail account, not linked to your main acct & a hobby phone which you shut off & keep separate.

And be stern about it. There is no excuse for her behavior.
As already mentioned, do get a hobby phone and keep it turned off and hidden until you need to use it. Get a hobby only email address.

Don't ever think your information is discarded after the session is over. ALWAYS assume that emails and phone #'s are stored regardless of what the provider or agency says.  

If you want to keep seeing her then ask her to contact you only via a clean hobby email account, or if you get a hobby phone.

If you don't care, ask her not to contact you at all, but don't be an ass, as you don't want her getting her panties in a wad and trying to cause trouble.
