If you’re planning on ending the relationship, every day you wait, you’re wasting their time, too. You should be especially sensitive if you’re dating a woman who is hoping to give birth to her own kids. You’re underestimating her opportunity cost of being with you. The longer you put off breaking up with her, the less time she has to find a new partner and build a family. The kindest thing is to give her a clear answer so she can move on and find someone else.
