help with finding a manga!

The cover was the main character crying while eating from like a top view if i remember correctly. The story is about the lady finding out that her husband is cheating on her with his subordinate(?), so she ends up divorcing him and moving back to her mom's place. As soon as she gets there, i think her mom says that she's gonna be traveling and leaves her bento shop for the main character to run. Main character has three siblings that don't help her at all, two sisters and a brother. last update i remember is that main character finds out that her mom has been traveling with a boy she used to feed a long time ago, and that her health is quickly declining. i forgot to mention this, but main character meets a guy while running the shop and i think she has a crush on him? The crush is dating a foreigner that he doesnt take seriously, and main character's brother has a crush on the foreigner. Hopefully this makes sense, i tried not to over-explain it by adding too much information;;
