Trust ?

Joy • just me & you little one 💚Waiting on my babyboy 💙
So the father of my son is trying to come back in to my life but I don't understand why now he's said a lot of hurtful things to me I do want my son to have both parents but idk if I should ever trust him again I'm so done with all the stupid stuff he says to me then he thinks that sorry really helps the situation any thoughts ??
