Well for one we are up to snuggling on the couch, and hugs every other day. Come to think of it she lays her head on me a lot when on the couch. We still playfight a lot, and have lots of tickle fights. Things are far from being frigid between both of us. I am happy for that.
Just two days ago she tried to punish me with no sex for two weeks for not turning off the AC in her car. I told her that sort of punishment would not help me remember to turn it off, and that's why we have such intimacy problems, and that I would not tolerate that sort of thing. She apologized a few minutes. So yeah that's definitely a measurable. Also no using the threat of divorce to win arguments. Now whenever she says that I just tell her, if this issue is so important to you that you want a divorce go ahead. (the issue usually is not, and this behavior has dramatically decreased).
I'm also expecting ml about 2-3 times a week. It has to be good ml not pity sex or duty sex. Once she meets these and other benchmarks, we can keep moving forward.
