<human>: Can you provide a brief overview of the text?

I have been talking to this guy for a couple of months.  He's showing a strong interest in me and I'm beginning to like this person but there's one thing that bothers me: my biological clock.

He's in his mid thirties but for various reasons he's only a year and half into his new career.  Assuming we become serious, I'm afraid by the time he's ready to start a family I will be too old to give him children.

He obviously knows how old I am.  Last weekend we touched lightly on this subject and I told him it's probably not going to happen to me because of my age.  He vaguely mentioned 40 being a cut off for most women.  We're not yet close enough to discuss things of this nature, so this is all that had been said at the moment.

He still talks to me as before.  I'm not sure what he's thinking and don't know how to find out what he wants to do with me.  Any thoughts?
