The resolution could involve Chloe herself playing a key role. She could choose to help Oliver overcome whatever made him hurt her in the first place. Maybe she discovers that Oliver was being manipulated by someone they both know. So, instead of holding a grudge, she teams up with Oliver to expose the real villain and in the process, they rebuild their relationship.
One way is through communication. Oliver realizes his mistake and sincerely apologizes to Chloe. They sit down and talk about what led to the situation, and Chloe forgives him. Another way could be that Oliver has to go through some sort of redemption arc. He does heroic deeds to make up for what he did to Chloe, like saving her from a real danger.
Perhaps a magical or alien - related solution can be found. For example, there could be a special crystal or a being with the power to reverse the damage Oliver has done, both physically and emotionally. Or, Oliver could sacrifice something of great value to him to show Chloe how truly sorry he is. This sacrifice could be his powers, his wealth, or his reputation among his friends in Smallville.
Well, perhaps Oliver has been poisoned in a way that affects his mental state. This poison could make him paranoid and see Chloe as an enemy when she's really not. Or, in a more complex plot, Oliver is trying to protect Chloe from a greater danger but his methods are misinterpreted and end up hurting her. For example, he might be trying to keep her away from a powerful enemy by pushing her away harshly.
Clark might be initially shocked but then very supportive. He would probably offer his help in any way he could, given his own experiences with dealing with extraordinary situations. Lois might be a bit more outspoken, giving Chloe advice on motherhood and also teasing Oliver about becoming a dad. Tess could see it as an opportunity to use their situation to her advantage in some way, but eventually come around to being supportive.
There could be a fanfic where Chloe gets pregnant by accident with Oliver in Smallville. At first, they are both shocked and a bit scared. But as time goes on, they start to see it as a new beginning. Oliver might have to face his own fears about being a father, while Chloe could be worried about how her pregnancy will affect her work or her friendships in Smallville. Eventually, they grow closer as they anticipate the arrival of their baby.
Definitely Clark. He has always been a central figure in Smallville. His friendship with Chloe and his acquaintance with Oliver make him a natural addition. He could offer his super - strength to help protect Chloe during her pregnancy if needed, and also give Oliver some advice on being a good partner and father based on his own values.
Maybe a story where they discover the pregnancy in an unexpected way. Like, they were on a mission together and Chloe starts feeling unwell. After some tests, they find out she's pregnant. Then it could be about how they break the news to their friends and family in Smallville. Lois might be overly excited and Clark could offer his support in a very Clark - like, selfless way.
One possible plot could be that they face challenges from their families. Maybe Oliver's family has certain expectations for him and the baby, and Chloe's family is worried about her future. Another aspect could be how they balance their superhero/vigilante activities with preparing for the baby.
