Time to learn how to see your daughter as an adult, even if she makes bad choices. Remember - you raised her. That means giving gradual responsibility, starting at a young age, so that by the time they leave home they understand what it is to be an adult.
Hopefully you can sit down together and negotiate calmly. The only ultimatum you should give her is that she can't have it both ways, taking her child, leaving her child. This new man probably won't work out either, but don't tell her that. Work out a maximum and minimum and some other ground rules, on paper, talking calmly over the dinner table. If you don't both work on this, you both lose.
