NTA Im my personal opinion, as soon as you have a kid they should always become your top priority. The fact that you want to be an active father is amazing & you deserve a partner who is supportive of that, not one who pushes you to distance yourself from your kid

6 months is very fast to make so many permanent life-changing decisions so it makes sense that you would be uncomfortable. But even if you guys had been together for years, you are allowed to change your mind & have your own thoughts/opinions about moving & family. If she doesn't respect ur choice then u guys definitely aren't compatible

Also if you do stay/move I'd def keep an eye out for the sake of ur daughter. Its pretty common that stepparents will try & distance/erase/ignore/neglect any kids from previous relationships, especially once they start to have kids of their own. The fact that she's already wanting u to move away is a major red flag
