Philo of Alexandria, and other Jewish writers from the early to middle first century, never even mentioned the Christians. Josephus, a former Jewish priest, then military leader and historian, writing late in the first century seems to have mentioned Christians briefly and somewhat favourably. So, we do not really have much information about how the Christians and Jews treated each other, apart from a few references in the New Testament, although there seems to have been tension between the two religions from early times. The Christians maligned the Jews for the death of Jesus. After the destruction of the Jerusalem Temple, some Christians seem to have seen their religion as the natural successor to Judaism. They were also competitors for converts among the pagan or gentile population. Towards the end of the first century, the Jews responded by banning the Christians from their synagogues and requiring worshippers to condemn Christianity, as evidence that they were not secretly Christians.

the sign of a fish...
they shared allot of stuff with each other
They both didnt understand each other
If you're a Christian yourself, you have shared beliefs, not least about the way you relate to each other. There are different types of Christians with different beliefs and that can cause problems. If the other partner is not Christian, there are few advantages as there will be differences over things both consider very important.
