husband looking at other women

I always knew my husband watches porn (he never admitted to it but I just knew) and never made a big deal of it but one time we were in the middle of having sex and my my 3 year old daughter was in the living room and all of a sudden started screaming so I ran to check on her. When I came back I found him watching porn on his phone but pretended like I didn't see anything. Now he's away for work for a week, he asked for a sexy picture but I had a super busy day and didn't get a chance to do it then he said that "he finds himself  watching porn and looking at pictures of women online" because I'm not giving him what he wants. I feel SO heartbroken and completely disgusted. Do your thing but don't tell me about it!!!
