I just used urm to change the cc stat to what I needed to unlock them all. Thankfully, I did so, as I did not know that we could get a different scene with Lori, one a bit more intimate and where she seems to be really falling hard for our boy Lincoln. After, I went back and made the right choices to make that my canon.
The mistake I made was kissing Ronnie Anne when they first arrived at the big city. The other choice required, I had already chosen to go to the restaurant for Lori, as I felt that she would have been more important to our boy, even without any relationship/sex involved, just love for your family usually supersedes love for a girlfriend. Maybe after you stablish your own little family with a wife/husband, the lover will take on a little more significance than your parents, brothers and sisters.
