Im glad you noticed that NGS is a huge resentment builder and marriage killer. Of course I read NMMG after my WW left me and I realize it now but I guess better late than never.
You will find a lot of LH19's stuff follows along what Corey Wayne would say on youtube, he has a very agressive take it or leave it approach, but something he says is totally worth putting in your pocket especially regarding NGS and it is "A relationship is about giving, you go there to give and not to see what you get in return"
Good job connecting the NGS and resentment its big.
T:11 M:10 K: D5, S7 BD: 9/1/20 WW continues to break up and recon with OM. I paid last fees and pushed the D 5/3/2021 Default Dissolution granted 8/5/21. Glad my D was not busted.
