Went thru my husbands phone should’ve done it sooner ... found pictures of some girl

I’m so hurt he’s been making me feel like shit for the shit he’s doing behind my back .. what kind of man does this? And to his wife that is 36 weeks pregnant, we had an ultrasound today at 10:30 and the top picture he saved today at 9:21 I had just gotten in the shower at that time we’ve been fighting and now I know why. Waiting to ask him tomorrow when he’s sober what the fuck is wrong with him and the fact is she might work at his job in the plant.. and she’s prettier then me we have a three year old son and one on the way a babygirl. And he does this 💔

****UPDATE****

Well he was getting ready for work this morning and I got up to pee nothing was said at the moment so I just sat on the couch waiting for him to leave so I could lock the door and turn the lights off. Before he said I’m sorry about last night, I stayed quiet for a second he asks “so you’re not gonna forgive me?” So I asked him who the girl is on his phone and of course he says “it’s nothing” and walks out. I bust out crying, he comes back in and sits on the couch but away from me and says it was nothing I thought we were done we never did anything. I kept asking for her name he said it was nothing. I said if it was nothing you wouldn’t be trying to hide shit in your phone and delete shit. Who the fuck is the bitch? And then I said she obviously works in the plant with you and you still talk to her if she sent you a picture yesterday. So as I lay here with my son right next to me and I can do is apologize to my daughter because I know she feels all this all my pain. 💔
