just change you girlfriends name with one of your mom's friends and see what see does then.

This is confusing. If your mother is "dropping by," she doesn't live with you, yes? And if that's the case, how is she reading your texts? And if it's through some kind of smartphone software that I'm just not familiar with, why not just tell her to get lost (in so many words) when she shows up unannounced after spying on your phone messages? Learn to defend your boundaries OP. Your girlfriend is probably suffering over your latent mommy issues too.

How does your mother keep getting ur phone? What kind of person are you?

Explain boundaries to her. Then, next time shes getting ready to get it on, cockblock her

That's why my phone has a password.

What is a rubber?

somebody needs to choke a bi**h

58, a condom

It's downright laughable that you think just because someone is at the age of consent it means they're actually mature enough to be having sex. Only an immature person would think that's always true. I'd say most are not truly prepared for the responsibility at 18, and almost none at 16.

Maybe skip the texting and move to Facebook messaging? IDK. I've never PLANNED on having sex, if it happens, it just happens and that's that.
