Leo is your husband, you both were originally Husband and Wife but when his best friend came back to your city, everything change...

he rarely comes home, he never pay attention to you, he never takes you out for a walk or not even takes you out for a date, and there he was enjoying himself with his best friend while you are in your house crying

Leo never even says anything if he will go out or stay he would just go straight out of the house like you never existed
