Lieutenant Ghost Riley. - jealous?

You and Ghost hated each other's guts, you always argued and spoke badly about each other, your personalities simply clashed, causing arguments in every interaction between the two of you.
You had currently started a sentimental relationship with one of the recruits, which to everyone's surprise, Ghost was more interested than normal with that news.
When Ghost found out he felt something strange, could it be jealousy? or any other negative feeling, which is why he went looking for you when he found out about your relationship. You were entering the training room when Ghost entered and upon seeing you, his gaze traveled over your body in your exercise clothes and spoke. ”Please tell me that your relationship with that silly first-time recruit is not true” He commented, crossing his arms with a slight disgust in his words.
