Hello
It's difficult at the moment to answer EEA questions when the migration project is in November (I understand that your partner lives and works in Ireland at the moment. He is not in the UK).
In October 31st, there should be a Brexit. Deal, no Deal? Brexit, no Brexit? No one knows for sure at the moment. But there are major changes coming that will affect your project.
Depending on how the situation evolves, your husband won't be able to come to the UK in November and exercise Treaty Rights then bring you in (at least it won't be as easy as it is now). He would have to go through other routes that are not very well defined at the moment.
There is the
European Temporary Leave to Remain. The scheme will open at one point after the Brexit and will allow EEA nationals wishing to stay longer than 3 months to register then bring their family at one point.
There is a lot of uncertainty at the moment but EEA nationals who enter and exercise Treaty Right before the Brexit would have easier and clearer path towards settlement.
If your partner wants to leave Ireland anyway, why not moving to the UK first (before the Brexit) then marry you later in November. But at least, you will have stronger situation when it comes to immigration.
