FMC traps MMC into marriage, realises she fucked up because he’s cold / in love with someone else, tries to leave, MMC panics and fights to win her back

Hii, I am looking for books with this specific angst setup. FMC traps or pressures MMC into marrying her maybe they are caught in a compromising position (if HR), forced by reputation, family pressure, or circumstance. After the marriage, she slowly realizes she completely fucked up because he’s emotionally distant, cold, or possibly in love with someone else.

The guilt hits, and instead of clinging harder, she starts withdrawing emotionally or tries to leave because she thinks she never should’ve forced him into this and that she’s standing in the way of his happiness. That’s when the MMC panics. He can’t stand the idea of losing her, realizes far too late that she’s the one he wants, and actively tries to win her back

I am open to anything except I don’t want cheating. If MMC is in love with someone else, I don’t want their relationship to continue after he marries FMC. Thank you!!
