is it a good idea to exchange facebook/twitter and email passwords with your gf of 2 years?

[MARLIN]

No, definitely no. She can read your postings and see what is happening. There is absolutely no reason for her to have passwords.

There is either a trust issue with her or she is making a power play. You need to look carefully at your relationship and see from the past which one is true. If you are honest, you will see that she has been doing things like this to you since you got together.

Its not a matter of privacy, you have nothing to hide! Its a matter that she wants or needs to have you give up some more control of your life to her and her desires. Why, I don't know.

Think seriously about what all this means and how its been playing out.
