Is going on my ex gfs fb account a bad idea? when im not over her?

[Selena]

oh man, this is very bad. I mean i didn't even have my ex's password but i would obsessively visit his profile a few times a day (at the begining of our breakup)..and that was already pretty bad because i assumed any and all girls posting on his FB were potential new gfs...anyway, point is i made myself sick with it. i eventually removed him from fb for the sake of my sanity, but then started asking a mutual friend to keep me updated until she eventually told me to snap out of it and refused to provide me with any more details.
so yes you're on slippery grounds, the best thing for u to do is to actually email her yourself..orrr have someone hint to her that she should probably change her password. this would ensure that you do not have access to it.
