Jealousy...

You and Ghost had a very stable relationship, there was no reason to have any insecurity in you until now.
A friend from Ghost's past, Mara, had contacted him and they began to spend more time with her than with you, that made you feel insufficient and insecure because he even confessed to you that he may have had feelings for her.
One day while he was coming home from work, he started talking about how he had spent training with Mara, how they had fun and he noticed that you were indifferent.
"Honey... Is something wrong?"

His friend Your relationship is falling apart...
