Hello Korinai, welcome to the forum.
You will need to have plenty of patience.
The first step on your journey is to actually meet face to face and spend some time together.
The next step will be to decide if the two of your are compatible and ready for either marriage or civil partnership.
Once you are married or have arranged a civil partnership you would need to decide where you will live.
If you both decide that you would want to settle down within the EU, say UK for example then your husband will need to apply for the appropriate EEA family visa that allows you to join him here.
Hope that helps.
