Clary might react with a sense of numbness at first. She's pregnant, which is a huge life change on its own, and then to find out Jace has cheated. She could withdraw into herself, not really knowing how to handle it. As time passes, she'll likely start to feel a deep sadness. She might cry a lot and feel like she's lost not only her relationship but also the future she had envisioned with Jace. However, her pregnancy could also give her the strength to be more independent and start thinking about building a new life for herself and the baby.
Jace will probably face a lot of guilt. His cheating not only hurt Clary but also has implications for the unborn child. He might find himself ostracized by their friends who side with Clary. Also, his reputation within their community in the fanfiction world could be severely damaged. If he realizes his mistake and wants to make amends, he'll have a long and difficult road ahead to earn Clary's forgiveness and trust again.
It would change in many ways. They would go from being carefree high school sweethearts to having a lot of responsibilities. There would be more arguments as the stress of the situation builds up. But at the same time, they would also have deeper moments of love and understanding as they face this huge life change together. Jace might become more overprotective of Clary, and Clary would need Jace's support both emotionally and physically.
Their relationship would become more centered around the baby. They would have to make decisions together for the sake of their child, which would strengthen their bond.
The relationship would evolve significantly. Before the baby, they were mainly focused on their own adventures and relationship. But now, they are parents. They would need to support each other in different ways. For instance, Jace might be more protective of Clary and the baby. Clary would be more nurturing, and they would both have to learn to balance their duties as Shadowhunters with their new family life.
Clary and Jace's love is a complex and passionate one. They meet in a world filled with shadowhunters and demons. Their initial attraction is immediate, drawn to each other's strength and beauty. However, they face many obstacles. There are secrets about their families and their own identities that keep getting in the way. But through all the trials, their love endures as they fight side by side against the forces of evil.
Well, I think in their married life, they would wake up early. Jace would probably be the first one up, making coffee for both of them. Then they'd get dressed in their Shadowhunter gear. During the day, they might be apart on different missions sometimes. But when they are together, they would hold hands and walk around the Institute, checking on the new recruits. At night, they would go to bed early, with Jace holding Clary close, protecting her even in sleep.
They communicate openly. Jace and Clary have been through a lot together before getting married, so they know the importance of talking things out. If there's a conflict, they would sit down and listen to each other's side of the story without interrupting.
In such a fanfiction, perhaps Clary would have to face the challenges of pregnancy alone at first. She might struggle with her emotions, feeling abandoned by Jace.
In this fanfiction, the development might involve Clary's friends trying to reunite her with Jace. They could see that Jace had his reasons for leaving and try to make Clary understand. On the other hand, Clary could be so hurt that she refuses to listen. Meanwhile, the pregnancy progresses, and Clary has to make decisions about the baby's future, like whether she wants to raise it alone or consider adoption. There could be a lot of emotional turmoil and growth for all the characters involved.
In this fanfic, the pregnancy could be a sign of hope for the Shadowhunter community. Clary and Jace, being two important figures, are now having a child. Their journey could involve seeking ancient knowledge from the Silent Brothers or the Iron Sisters about how to ensure the health of the baby, considering their unique genetic makeup as Shadowhunters. Along the way, they could strengthen their relationship even more as they face the challenges together.
