sorry dude i was practicing my speed reading, but if she straight up asked you i wouldve been like "hello, im a red flag". but, that shouldve been followed by long and deep thinking on your part. she has so many kids it sounds like shes looking for a baby dady, no offense. what are her views on abortion? i know you might feel guilty for a while, but its way better than fucking yourself for the long run. i would personally be way more scared of having a kid.
On reading your situation my honest opinion is you're a lunkheaded child who should have pulled out, you'll get used for the rest of your life by your "free spirited" wife and eventually catch her cheating on you. You asked.
