Is it normal to be jealous of your boyfriend's daughter?
Feeling jealous of your boyfriend’s daughter can happen, especially if you feel left out or unsure of your place. The feeling itself doesn’t make you a bad person, but it’s important not to make his daughter compete for his attention or affection.
A child can take up a lot of a parent’s time and attention, and that can stir up insecurity—even when you know she isn’t a rival. If you’re joining an established family, it may take time to figure out where you fit.
Try to name what’s underneath the jealousy: maybe you want more time together, reassurance, or clearer expectations. Talk with your boyfriend about those needs without blaming his daughter. His relationship with her is a parental responsibility, and she shouldn’t be pressured to step aside or made to feel unwelcome.
If the jealousy is turning into resentment toward her or causing repeated conflict, take that seriously and consider getting support to work through it.
