pls help me find this historical/ travelled back in time comic

so i remember the ml being cold and basically never treating the fl right. in the end the fl died of smth and he still didnt care or smth until his son went astray and he realised what a nice wife she was? he makes a deal with some person to turn back time, and now both the ml and fl went back in time. the fl is strong and wont give in to the ml ever again and the ml feels guilty and wants to correct all his past mistakes. (i could have told some information from a different comic as i read it long long ago but i remember very well both of them went back in time)
