Should I suspect??

So about 3 weeks ago I came over to spend the weekend with my father and brother and sister. My husband was supposed to show up that sunday at 10:00 A.M. He showed up 2 hours late. When I got home that night I found he had watched all kind of porn that morning. It bothered me because he lied to me about it and he hadn't had sex with me in a really long time. I found he has been doing that since he stopped having sex with me. We got in an argument and he said he wouldn't do it again. Well we haven't had sex in 2 weeks and I am at my dad's again. He was supposed to be here at 10:00 A.M this morning and was 2 hours late again. Should I be expecting to find porn again?
