Hey LaLaa ,
I’ve been there , I know how much this hurts, believe me when I say that the best thing you can do is walk away.
You only have more hurt ahead of you , right now he has no empathy for you . He has no regrets for what he does or says . You will be somebody he can blame for his use , you will be the nagging partner.
As sad as it is , let him go .
Sending love xx
