Because Ireland wants to be independent, so there is no reason for it to join Another Country.
It is unlikely Ireland would join the Schengen Area unless the UK also joins. There is currently a passport-free area made up of Ireland and the UK. If Ireland were to join the Schengen passport-free Area without the UK it would mean passport controls on the border with Northern Ireland, which would be politically unacceptable.
The UK is comprised of England, Scotland, Wales and Northern Ireland.
Great Britain is composed of England, Wales and Scotland. The UK is Britain + Northern Ireland. To join the EU as Great Britain would be to exclude Northern Ireland from the EU.
Ireland became part of it, in 1801. Ireland then gained independence in 1922, though not all of it left. Most of it did, but Ireland was partitioned, creating what is now called the Republic of Ireland, which is not in the United Kingdom, and Northern Ireland, which is in the United Kingdom.
Ireland became part of the United Kingdom in 1801. At that time it was all of Ireland that was part of it. Northern Ireland did not come into existence until 1922. At that time it stayed part of the United Kingdom, while the rest of Ireland became independent.
The United Kingdom, along with Ireland and Denmark joined the European Common Market in 1973.
It could, but as a separate independent country there is no reason why it should want to give up its independence and do so.
