<human>: Can you summarize the given text in a few sentences?

I've always been undecided with regards to whether I want to be a parent or not. I always assumed that the urge to start a family would show as I grew older, but nothing is happening so far. I don't really see the benefits of having kids, while the tradeoffs and responsibility is more intimidating than ever.

My girlfriend has always been certain that she wanted to give birth at some point. We had a serious talk during the easter about the issue, as we realized that the clock is ticking. We've had the talks previously, but it has always ended with me "hoping that I will be ready" at some later point in time.

Well, out of fairness to her, the time is up. Basically, I need to either promise her that I will be the father of her children within the next couple of years, or we need to break up to give her a fair chance of finding the right guy who will.

I am not sure I am ready to become a father. I am not sure that I ever will be, nor that I actually want to have children. I love my girlfriend, and want to keep our great relationship. Basically, I am about to potentially make the biggest mistake of my life, but I don't know whether breaking up or staying is the mistake.

Have anyone been in a similar situation who can offer advice? What hard questions do I need to ask myself?
<bot>: I need to either break up with my girlfriend, or start a family with her. I am not comfortable with either option.
