Husband watching porn..

Is it wrong of me too feel like shit that my husband watches porn? I found gross porn on his phone today. Things like squirting, lesbians and he even typed and searched "sexy brunette with nice tits". It makes me feel so shitty because I just had our son so my boobs aren't perfect anymore. They're starting to sag and all he cares about is nasty whores with nice tits. I was gone for 4 hours today. He couldn't have waited until I got home to get laid? No. Instead he waited until the baby went back to sleep to jerk off. I feel like I'm not good enough and that I'm just disgusting to him anymore. I'm so close to leaving because I just feel like he uses me for a babysitter for his 2 damn kids.

Update: I have talked to my husband and simply asked him if he would stop watching porn. He said that he would, but whether or not he actually will only time will tell. And yes, I am very insecure. I have been before the baby and my husband knows that. He knew who he married and what he got into. I have asked him if he wants to do anything differently in bed and he has told me no. So no, it's not just because I won't try something new. He knows I'm up for anything. So thank you for the people who were actually helpful and not giant a-holes

Update 2: I've been trying to fool around with my husband for the past couple of days with out any luck. Didn't seem like he wanted anything to do with me. So when I got home from work I checked his phone and sure enough this is what I found. He's trying to claim he never watched the video, which is clearly a lie because he's 5 minutes into it?! I'm officially done trying. I hope he's happy fucking himself because that's all he going to be doing. I'm done having sex with this man so I hope his porn was worth it because that's all the action he'll be getting.
