How can I find out my gmail account password?

How can I sign out my Gmail account from my boyfriends blackberry?

• While on vacation I used my boyfriend's blackberry to access my gmail account. I did not realize the box saying 'keep me signed in' was ticked when I entered my user name and password until I used it the following day and did not have to sign in since both pieces of info were saved on his cell. At that time I did not know how to log out of the account as I was not fimilar with a blackberry. My girlfriends and I communicate via email and I don't want my bf reading their emails about their relationships, marriages, sex lives, etc. I also use this account for everything else - apply for jobs, etc. I read this article where I did the following http://www.watchingthenet.com/how-to-find-out-if-someone-has-access-your-gmail-account.html but I'm still logged in on my blackberry. I changed my password already but it did not affect my account on my cell. Please help me. Serious answers please,thx!

• Answer:

  there should be a "log out" option on the blackberry. just ask him to log out of the account on his cell or ask him to see the blackberry, open gmail and then log out of the account. i will say that it is weird that its still logged in after you changed the password. ...honestly, that should have solved your problem right there.
