Context: Me 25; her 23, 5'1" and tiny.

I had to break up with a lovely LTR-worthy girl beacuse she is incompatible with my life goals in ways that can't be changed. Here's what I wrote her:

"I am never going to marry, and I am not going to have kids with you. I don't have enough money, and you are too old for us to give them everything I want. Also, you are too physically small and too redheaded to risk having sons with. It would be unfair to them. That said, your soul is ideal for lifelong monogamous partnership and familial bliss. You are wasting your valuable fertile years fooking me. You ought to find a guy who is ready to start a family with you, and get him to commit. Make the most of your long red hair and tight pink pussy while you still have it, because it's all down hill from here. Don't wait until you late twenties like your friends will. You will make an excellent wife and mother, and you should use you family as a source of meaning in your life. The time we spend fooking drains your ability to enjoy future domestic happiness with someone else. I feel (a little) guilty every time I hit your cervix because I am taking something from you that you can never get back. I would be happy to monopolize you forever, but I will never give you children, and ultimately I will give them to some other girl. I really want to keep you around, since it is great for me, but it is not in your best interests. The best thing for you, as far as we are concerned, is to not see me again."

As gay as it sounds, I really want to take care of this girl forever, and happily would. But getting her pregnant would come at the expense of my children, which seems like a unfair choice for me to make on their behalf.

(The only practical solution I can see is having multiple baby-mommas who voluntarily terminate their legal custody of their children, but still live in my house as my dependents with our children).
