He hasn’t asked about his son at all

Wednesday night I found out my baby’s father is sleeping still around with the women who he was cheating on me when I was pregnant with our baby. I kicked him out at 4 in the morning with a bag full of his things. Since that day not once has he asked how our baby is. I texted him Thursday telling him that our sons is going to the hospital but I didn’t expect him to reply because he’s a coward. Itll be a whole week tomorrow and he hasn’t say anything. I’m so sad. I’m so heartbroken. I want to reply to him and lash out and tell him how shitty he is but what’s the point. At this point I need to let that man go. But how could he not even once call and see how our son is...
