It actually goes the other way around. However, Christianity and Judaism parted ways the day Christ rose from the dead. It is worth noting that many Christians do not necessarily view themselves as being terribly separated from Judaism: the belief here is that Christianity is the fulfillment of the promises of Judaism, rather than a replacement or separate religion. Adherents to Judaism tend to view the matter significantly differently. The term 'Christian' did not exist until a decade or so later, however, and the Roman government viewed Christians as a Jewish subset for a short time after that. In a way, the answer depends on who you ask, but these are the most common answers you will get from any given group.
Christianity and Judaism was split in Roman eyes after the imposition of the "Fiscus Judaicus" under the emperor Domitian and the later reform of the fiscus under the emperor Nerva. This fiscus was a tax on all Jews in the empire after the destruction of Jerusalem. At the beginning Christians were included as they were a Jewish sect or offshoot. In the year 96, after the reform by Nerva, a legal distinction was made between Jew and non-Jew. Judaism was an accepted religion and Christianity was an illegal one. This parting in 96 is interpreted as the historical break between Christianity and mainstream Judaism.

Without Constantine's decision to adopt Christianity as the religion of empire, Christianity might have remained a minor religion in the Roman Empire. Without Constantine being followed by ruthless Christian successors as emperors, his establishment of Christianity in a favoured position in the empire could have fallen away, as former pagans who became Christians for political and financial advantage returned to their traditional faiths. It was the dynastic succession of Constantine that provided the circumstances for Christianity to become a world religion.
Christianity became the official state religion under Theodosius I in 380 AD. Many people erroneously think that the emperor Constantine made it the official religion, but this is incorrect.
