Hi, how much pressure is her biological clock putting on the situation right now, i.e. how old is your partner? How old are you? How long would you like to wait before having kids? If she is 40 and you want to wait another 10 years, then this would not work unless one of you bends. But if you are 20 and she is 30, and you want to wait only 3 years, then it seems like it might work. You have to look at what you want--do you ever even want to have children at some point with this woman? If the answer is yes, then you might need to compromise, because fertility lasts only so long. And if the answer is no, you should let her know, so that she can move on with her life or decide if a childless life with you is acceptable to her.

I think going to a counselor for help sorting this out is a good idea.
