Searching for a manga

So I cannot remember a lot the only thing I remember is from the backstory of an character sorry because of that, anyways it a highschool female who wanted to go home and needed to go over a bridge a guy then r worded her long short story she got pregnant needed to marry him and gave birth to a child while being depressed and then a few years later the now husband comes back and r word her again, she got pregnant again. I think the older sibling has like nearly no emotions or something like that

I just really need to know what happen to the bas*ard of husband and the ending of the original story because I couldn't finish reading it
