my relationship has took a rocky turn here in the past week, my daughter's father recently moved out of the house this past saturday & today he saw our daughter for the first time since he's been gone & she did nothing but cry the entire time; I don't know know what I should do, it's like we're both just a burden to him & his life. any advice?
