My (23M) girlfriend (22F) doesn’t want to have kids in the future.

I love my girlfriend to death. We have been together for close to a year now. She is my better half but we have some fundamental differences about some things. She doesn’t believe in “dealbreakers” and I do. In her opinion as long as both people love eachother they can be in a relationship, even if they have differing options about things.

At the start of our relationship I think the topic of kids were brought up and she said something along the lines of “right now I don’t want kids but in the future I would be open to it”. Which was the same for me, we are really young and right now I don’t have any plans to have kids, however I would be open to it in like 10 years time.

We had a conversation yesterday after the topic was brought up again on how many kids each of us wanted. She said she didn’t want any and didn’t want any in the future. I responded saying that I thought she said she would in the future because we had talked about that earlier and she said I was mistaken as she thought I said I never wanted to have kids either. She says it would be bad for the planet to have kids as well.

She said at this moment she can’t know what she’s going to feel in 10 years time so she can’t give me an answer for it. It’s also not something she’s actively thinking about as she says she wants to live in the moment and worrying about what future us will think or feel doesn’t make sense because I don’t know how I’m going to feel in 10 years time either.

I have a lot of anxiety about this topic and I think I feel pretty strongly about it but what she’s saying is right. I don’t know what’s going to happen in 10 years or how I will feel either or what kind of place we will be in our life. I have also done a lot of digging on Reddit and the majority of people are saying “if this is a dealbreaker just break up with them” which I think is pretty extreme but I guess it makes sense that if nothing changes in 10 years time maybe I will harbour resentment. But I don’t know if I will or won’t.

I’m also not completely sure if this is society or my parents telling me that I should be having kids or something that I want and if it is how can I make a move based on something that might not even happen in a long time as we are both young. She is also very strong willed and won’t really change her mind because anyone says so it has to come from her.

What would be the best method of dealing with this situation? I am very confused on what to be doing next. Is this too early to be thinking about this and is worrying about the future just harming me?
