Should I [39m] break up with my girlfriend [34f] who wants kids?

My girlfriend and I have been together for almost 2 years and we are really happy together. I have 2 teenage daughters from a previous marriage. I definitely want my girls to have siblings, but I do not want to have any more kids. My girlfriend however wants kids of her own, and I can't blame her for it. I feel really conflicted here. I don't want to break up with her, because I love her so much, but I also don't want to take away her chance of ever becoming a mother. What should I do in this situation? I asked her if she would consider not having kids but she was very clear that she wants kids and is willing to adopt if needed.<br><br>Edit: I don't think anyone blames my girlfriend. I blame myself for not asking her about having kids in the beginning of our relationship. I just assumed she wanted kids because she is a teacher. I feel really bad about putting her in this position and taking away her chance of becoming a mother.
