<human>: Summarize the given text in a few sentences.

I'm a 37 year old man who got too involved with his career a decade ago, blinked and realized he was nearly 40 and single. I decided to change my life. 

While I never thought I wanted kids or to get married - in fact, I broke up with women in the past who wanted those things while I didn't - for the past 18 months or so I have come to realize that I might be wrong about that.

I don't know how to describe it beyond this: I feel what I think is an instinctual urge to have kids. The topic has strayed so far afield from "want" as to be laughable. It has nothing to do with "want". What I feel is more of a need. 

As the last male in my line, it has taken me up until this point to feel this need to ensure that the line of my people continues. What's more, I feel a particular need to have a bunch of offspring. 

Accepting that this is the case with me now was easy enough.  But the bigger question is this: how do I figure out if a particular woman would be a good partner and a good mother? 

Truth be told, I haven't dated in the last few years. I finally had enough a few years ago of the type of women I was dating and decided to just focus on other things. Looking back, that might have actually been the beginning manifestation of this: wanting to move beyond casual dating relationships and onto a very serious and permanent one for the purpose of having children. I didnt realize it at the time. 

Anyhow, not knowing that type of woman - specifically, women who also wanted to have children and who weren't looking to just date - was a serious hurdle. In fact, it remains a serous hurdle. But as I'm not longer moving around all the time and have a far more stable life, I feel that may change.
<bot>: How do you pick the right woman for long term commitment, to give birth to and mother your future children, and where do you find such a person?
