Christianity means following Christ. But then you say Christianity is about having a relationship with God. Why is God the same as his son Jesus? I never understood the trinity and it simply doesn't make sense.. the word Trinity is not in the Bible, it is clear that God is God and Jesus is his son, and Jesus even prayed to God... so did he pray to himself? Why did Jesus say no one has seen God and lived, yet Jesus himself was saying those words to people on Earth.
But yes I believe in God and believe in Jesus- both mutually exclusive.
