I don't think they'll break up. I feel like that would derail Samay's plan of getting close to Maya. I don't know what his game plan is. He doesn't seem like the white knight. More like a dark prince. He has schemed and waited far too long to get back to Maya. He went into a relationship with Saanj deliberately to enter Maya's life with stealth. I don't think he will break it off so quickly. Samay knows how to play the cute guy. I think he will convince Saanj that he was powerless against the police and rouse her sympathy.
No I don't think saanjh will break the relationship because the prosecutor said that saanjh told him to leave the city but the police caught him. Plus samay did look like he was on ayan's side because he was hesitating while giving the answers. We know that he loves Maya and he will always be with Maya but saanjh and her family doesn't know that.
Saanjh will probably figure out about Samay and Maya and then she'll use him to find more about Mayas past and what she has done, either by asking him or by investigating his past. But I'm sure that poor girl is going to get hurt when she finds out about him😔.
