Leave my(31M) GF(32F) because we can’t agree on having children?

My GF(32) and I(31) have been together for a little over 5 years now. We have talked about some future plans and naturally children came up. I have always wanted kids, but she definitely doesn't and that's completely fair, but it seems like a compromise I can't make. I feel honestly selfish for thinking that I should leave because of this. It's not that she doesn't want them because of some hereditary health issue or anything, just a personal choice (just for context). On top of that, I own the house we live! in and I am unsure she could afford to online on her own right now because her work life is currently turbulent. I have so much love for this woman, but sacrificing something that I find so incredibly important seems impossible and it's honestly eating at me. I don't know how to approach this without making her feel like she's holding me back from the things I want in life, and I would want to have some kind of connection with her still. How do I approach this without making her feel like she's keeping me from something important to me and thinking she's not enough?
