I am not.

It does not.

Of course some other connection between my girlfriend and ex may be possible, but none exist or are record online to the best of my knowledge. The problem with this answer is that all of us have considerably more readily associated information, and even if there is a rare case of indirect connection, it seems unreasonable that Google would weight it so greatly so as to make it one of the 8 Wonder Wheel connections.
