Help advice please

Hi I’m in a relationship of 7 years. We have 2 girls and I’m pregnant with our third. In 2023 I found out when I was pregnant he slept with men and was sexting them behind my back which he confessed as being gay… 3 days later he retract that and said he was just curious I ended up forgiving him for our children’s sake anyway it’s tonight and I find out his still looking up trans women and watching trans porn and messaging trans I’m absolutely angry and thinking of kicking him out any advice please
