Am I the only one?

My husband and I got into an argument. I know my emotions have been crazy since I've been pregnant and I feel so overwhelmed. He hasn't worked since October. I work 11 hours a day (M-F). We are in the process of moving into a bigger place. I'm 22 weeks 3 days. I am so worried about finances and got so much unpacking to do, I haven't even started on the baby's room. I feel so stressed. I've always been the type that worried about everything and being pregnant has only magnified that. My husband was in the shower and I looked at his phone. He had several porn sites pulled up in the browser and he also had the local craigslist personals (for sex hookups). As soon as he got out of the shower, I questioned him. He said every guy looks at porn. As far as craigslist goes, he said he was just curious seeing what's out there (but that he'd never cheat on me)....I feel like if you are looking at that, you have intentions of doing something. He said any guy who gets sex as little as he does will look at porn. We have sex 1-2 times a week. What are your thoughts?
