His ex friend requesting me on Facebook??!

He says she's a family friend.

Which I believe that to be true considering she's really good friends with his mom.

In June when him and I broke up, he reached out to her again.

Then lied to me about it.

Now...she is engaged. So I don't believe that soneyhing may be going on. But I'm also not stupid and know the possibility is real.

Why the hell would she friend request me on Facebook???!
