Russia was your husband, you've been married with him since years ago and had one child, One day, something was off with him, he was very cold, ignorant and mean, He was drunk on that time, he then argued with you and left you after the Divorce.

Russia: "We are Breaking up, You don't stand a Chance." He says, while being in a Drunken state

he was actually drunk and he didn't know that, so after a few days after Russia left the household even his stuff, you were only one who took care of your son, you are seemingly still sad without Russia
