What did I do?

It really sucks finding out that you’ve been cheated on. Especially for the past 6 months!!! You’ve Lied to my face for so long. How could a man sleep at night knowing he’s messing around. How could a woman be okay with waiting for a guy to dump his pregnant gf, so they can be together. I feel so dumb!!!! You’re 30, not 18 or 25!! Never been so blind sided in my life. I gave birth to your daughter 7 weeks ago!!! PPD isn’t a reason to cheat. “You brought me down when you were depressed” My heart hurts and you never cared. Was I not good enough? What is it about her? You got carried away, and will have to live with the biggest regret by losing me. I Pray you get the healing you need. Now I have to be strong for myself and my daughter. Sorry ladies I just needed to get this off my chest.
