I realized that I have no butterflies in my stomach when it comes to my WW. I want that feeling, it is the best feeling in the world.
Instead of butterflies our WAS's give us something more akin to acid-spitting beetles in our stomachs Those fluttery feelings are part of the limerence phase though, so that's typically just present early in the relationship (for 6 months to a year). So don't fall in love with the idea of that feeling because it does eventually pass in all LTRs.
