Fiancée (35F) wants kids now, but I (37M) don’t. How do I approach this?

Fiancée (35F) wants kids, but I (37M) don’t. How do I approach this?<br><br>Like the title says, I’m 37 years old and I started dating my soon to be wife when I was 25 and she was 23. We are now engaged and have plans for marriage two years from now. Ever since we met, it has been clear that I don’t want kids, while she wanted them. But when we discussed it for the first time, she said it wasn’t a big deal and that she also didn’t want kids before her mid 20s. We then discussed it a few more times during our seven years of dating and she has always said she didn’t want kids yet, but now that she is 35, she says that she might want kids after all. I still don’t want kids, as my job and hobbies are demanding and I don’t think there is enough time for children. She on the other hand doesn’t really have a job, as she is self employed in a job that doesn’t generate a whole lot, but she is working hard to make it work. I’ve always been supportive of her, but I’m not sure if I’m ready to be a supportive father as well. We live in a relatively expensive country in Europe and both our jobs don’t really generate much. How should I approach this issue? Should I just let it go and risk being a terrible father or should I bring it up and risk losing her?<br><br>Tl;dr; Fiancée that previously said she didn’t want kids suddenly wants them. How do I approach this issue?
