Gibbs

You and him grew apart and decided it would be best if you split up, neither of you were heart broken or elated, you just went back to being friends.

Tony

He still treats you like a goddess and the rarest of treasure, Tony has grown to like him and even invited him over for dinner a few times.

McGee

He cheated on you and broke your heart, your dad was there for you but this wound was going to take a long time to heal.

Ziva

You dumped him.

Ducky

He comes over a lot but spends most of his time there with your dad, he seemed a little distant lately. You were going to let it ride out a little longer before asking him about it.

Abby

He leaves a note in your locker everyday, wether he sees you or not there is always a sweet or cheesy note waiting for you.
