My girlfriend (27) of 10 months wants to break up cause I (29M) dont want to be a dad.

I'm in a serious relationship with this girl. We met at work and everything was going well between us in the first 8 months. We talked about kids and she said she wants 2. I said I don't want kids at all. But she said it's fine since I'll change my mind once the time is right, and in the meantime we continue dating as normal, and I was ok with that. <br><br>A month ago she told me that she wants to break up with me because I don't want to be a dad. She said a month ago because she wants us to continue seeing each other at work and remain friends, and maybe in the future she'll change her mind about breaking up. But I don't want to be friends with her, I said. I want to be with her as a girlfriend, but I don't want kids. So she said 'sorry, but I want kids and I will not be with a man who doesn't want kids'. I'm very confused and saddened by her decision. Am I at fault here for not wanting to have kids? Shouldn't she have just ended the relationship 10 months ago when we first talked about kids? Why did she wait this long and allowed us to get this close, and now she wants to end the relationship because of kids? <br><br>What do I do here? I just want to be with her, and I want to be a bf to her. But I just don't want to have kids, and she is being stubborn about it. I can't even talk to her about it anymore because we had this conversation countless times. <br><br>Edit: thank you so much for the kindest comments. I really appreciate you all for taking the time to read. Many of you said I should've left as soon as she said "it's fine, you'll change your mind", and you are absolutely right. I should've left as soon as she said that, and maybe I would've saved myself from this heartache. I honestly don't know what I was thinking back then, but thankfully I'm moving past this painful time, and all of your comments made me feel a bit better. It's not easy, but with time I know I'll heal. Thank you all so much again for your kind comments. You don't know what it means to me. ❤️
