Snapchat issues

What would you do if you saw your boyfriend was subscribed to one of those porn models (whom he added AFTER we had a talk about him being subscribed to porn hub on there) BUT then told you to get over yourself, and stop acting childish after getting upset. He also thinks because he was honest with me that poof it makes everything ok now, I told him, you could be honest with me and say that you lost our dog, would that automatically make it ok? No. Just because you’re honest about something doesn’t mean you’re automatically forgiven. I am 12 weeks pregnant and he added this after we already knew, I’m assuming because there was about a week where I was so sick I didn’t want to have sex. He has screenshotted majority of her posts. Advice?
