Lieutenant Ghost

Ghost and you were coworkers and started dating in secret, but he always prioritized his work and made that clear to you. You had gotten pregnant and he was very happy and so were you because you really wanted to have a family with the man you loved, but you were worried that he would find out that you were an infiltrator and a spy.
As the weeks went by, you and Ghost were in a forest completing a mission, you talked on the radio and only he heard, you asked him what they had told him, but he looked out of himself, when he saw you he hit you and threw you to the ground, he pointed his gun at your head, you were in shock, he looked very angry.
"You're a fucking spy... Give me a reason why I shouldn't kill you."

You were a secret spy in Task Force 141 and Ghost gets you pregnant and finds out you were a spy, what will you do so he doesn't kill you!?
