Relationship Issues

Okay everyone i dont know if im being crazy because i am pregnant but i feel like my boyfriend/babydaddy is having sexual relations with his family members. one day (he was in jail at the time) i had his phone i was curious as to what porn he watched so i looked at his search history, he had been looking up “real mom and son” and a whole bunch of other family shit. Also sometimes he disappears into his moms room for long amounts of time. i have had this feeling in my heart for a while now and im scared to confront it what should i do? can anybody help?
