I’m not going to pile on you because our nicest poster got you pretty good. I just want to add that my guess part of your problem in your marriage is you didn’t listen to her. You’re trying to push Retroville on her when she’s telling you she can’t be monogamous. When someone tells you who they are believe them.
All you are doing right now is reminding her she has no romantic feelings for you.
I’m very curious as to why you have never tried to actually DB?
