Should I end this relationship?

Been dating a guy for 4 months. I can't really get to know him because he's a closed book sort of person, which he has admitted to being. I'm considering ending it, because I can't build trust in him due to him not being open. He said he's like that with everyone. I asked if In time, he opens up but he said "no , it's just how he is"
