I'm too single for this

There was this manhua I read ages ago and forgot the name of. It got discontinued so I deleted it off my list basically its abo. the story setting was sort of disease that wiped out humans except for the abo. The mc gets married to the unwilling ml, who has a child (he got SAd and that’s why he has that kid) when they were young they went to the same school and slept together once. Mc got pregnant but the baby didn’t survive (because of the disease) so basically the ml is awful to him, by the end mc signs divorce papers given by mls father and leaves, but he’s pregnant and then gets the disease(?) and they get back together. I’m sure I missed a lot of things but can anyone tell me the name?

I’m looking for a chinese(?) romance novel So there was this empress that was sent to the enemy nation with her son to be a captive then comes back to the palace with both her son and daughter dead and finds out that her two female cousins entered the palace as concubines and gets sent to the cold palace gets her tongue cut off (?) then poisoned and killed and wakes up as a younger version of herself and seeks revenge,(she has 2 uncles and her parents are off at war and everyone is scheming against her) meets a son of a duke(?) who’s interested in her after seeing her schemes, some stuff happens and she gets locked in their ancestral tomb or something and burns the place down and purposefully burns herself as her parents (the patriarch? Of the clan) comes back from the battleground. That’s about all I can remember rn I saw it on novelupdates but can’t seem to find it pls help!
