My girlfriend and I have a common friend. That common friend is my ex. Now as i had a date planned friday this stupid friend invited herself to the date WITH, and hear this, my girlfriends ex's friend. What you must know is that her ex is a crazy motherfucker and if he learns anything chances are I might be dead tomorrow morning... Now this action from my ex is fucking retarded and im pissed. That is all just wanted to shoot this out
I hope she isn't that self-indulgent to screw around with external affairs that no longer concern her.
If it is a good relationship though, you can always talk it over with your partner and she will understand the grudge your ex has against you. Take it easy, and remember those whom are not in your life are irrelevant (no matter how rude that sounds).
