How do you react if husband rejects you?

I initiated sex with my husband but he rejected me. Few times already. Caught him with a sh*tload of porn history on his phone FOR THE SECOND TIME after we got married. The first was just 3 months into our marriage. Now it’s been 1.5 years after our marriage including a 6 month old baby girl and he’s back in his world of porn again. And he didn’t even bother to apologise. Instead he gets angry and disrespect me. He disrespected our marriage. He made it seem like it was wrong for me to snoop on his phone. Which I usually don’t, because I have this mindset of the less I know, the better. But that day something moved me to check his phone. I don’t even know if he wants to have sex with me anymore which makes me wonder if I should even continue with this marriage. I did ask, he just kept mum and didn’t bother to talk about it at all.
