A little. Sounds like you're not crazy about the kid full stop - which is fine, they're not your kid, but she will always put her family first and rightly so. If you don't want to factor into that then you need to be honest. You're hurting her feelings more by withholding the truth. Focus on your own life and the direction you want to take - that takes courage but it's better for everyone in the end. We can't always have what we want but this situation is what it is, she has a kid, you're both not on the same page. You either push past it or part ways. But the kid will still be there regardless.
