Would you consider porn betrayal ? Read description first!

I don’t know how to feel I mean, I never thought my husband was watching porn behind my back. We have always had good communication and, great sexual activity. I’m two months postpartum and, there was the healing time plus me getting the IUD. I kind of feel betrayed because my body has been trough a lot, I’m a first time mom kind of going trough a small trauma I mean I didn’t expect labor to be soo painful and, I just feel like he hasn’t appreciate what my body went through to bring our daughter to these world. I need opinions advice please someone help me! My emotions are all over the places.. and worst part is that he said that it was a joke that he play it on purpose to play with me like I’m not stupid, I don’t buy that.
