So my bd and I had never lived together, just did the long-distance relationship thing. We barely knew each other when I became pregnant with dd. I couldn't move to be with him because I needed a job to pay my bills, but also needed the insurance. Well, just over a year later after having dd, I got the second surprise of my life and found out I was pregnant with ds. Well, apparently bd wasn't committed to raising these kids together, because while I was pregnant with ds, he got himself a new gf who herself has a child. He neglected to tell me about the new gf until after his visit after ds was born. Well buddy, if you want to play house and daddy to someone else's kid, but not your own 2 biological children, you'll forever be known to them by your first name from now on. Dad is a name & title you EARN - it's not going to be an automatic. From now on, all cries for "daddy" will be redirected and corrected to your first name. Strangers you want to be with YOUR children, strangers you'll be the older they get, the more formal your title; eventually, you'll just be known to them as Mr. Last Name.
