Why is my ex-boyfriends girlfriend adding me on facebook?

[Sarcasticbun973]

I just got a friend request from my ex boyfriends girlfriend on facebook. I blocked him a week or two ago so I could finally move on from our relationship and Ive only seen the girl in person once, so I don't understand why she is adding me.
I sent her a message asking who she was, just to play dumb but she didn't reply.

Either she wants to be ur friend, wants to stalk u, or wants to make fun of u -.-
I'd deny it if I were u, BUT it's up to u. I don't want to lead u in the wrong direction!

Probably trying to start problems.

What a total bitch,
DENIED lol, she probably just wants to make sure your not still having feelings for him and posting it on FB or she wants to make your life hell...
either way.. don't except.

[Bavani]

she wana keep track whether u gona steal her guy back or ur ex will go back to u or not....

[Aimee]

Shes a friend w-h-o-r-e, she wants a lot of friends on facebook..

[Gamer Chick]

ignore it
i wouldnt add her
u dont know her so why should you add her
likewise for her she only knows that u were his ex

id say just leave it hanging so it shows that she added u but is waiting for u to accept

She is seeking for attention. Or she want to be friends with you, since you're her boyfriend ex. I suggest you don't accept people from fb if you don't know them. She may also create a new account if you remove her.
