If I were you I would stop going out with him. He will go out with you for a while, maybe even years, but he will probably go for an arranged marriage later on. His family will put a lot of pressure on him and he will want a woman that he can dominate, will cook and clean for him, like a slave. I went out with one for 8 years, introduced him to my family but we never went over there to his family. During the whole 8 years they kept trying to get him to agree to meet women that the family had chosen for him. I was considered nothing but was useful as he was living in my house, paying not a lot towards rent and kept being in and out of jobs.
If you want to spare yourself a lot of pain you should end it before it becomes too serious or you get pregnant. Believe their culture is so inbred in them and so important to them that it will always come between you two
