I understand why you would would ask. Man do I understand, lol. But saying you were, "just trying to lighten the mood"? Really? So if she had said, "Yee-haw, cowboy, let's go for a roll in the hay!", you would have said "Just kidding"? Lol.
As much as it hurts, you have to accept that it's pressure on your W and it won't do anything to loghten the mood.
I can't blame you for trying. My W said on BD that she wanted to live together as "room mates" and that ML could continue, but that evaporated before I could even take her up on the offer. And I'll admit, I asked her a couple of times about a "fairwell party" but she made a face like I asked her to join me in a plate of escargot covered in peanut butter sauce, lol!
But I regret that now (yet another in a line of rookie mistakes), and you'll come to understand why as your sitch progresses. It can still turn around, but putting pressure on her will have the opposite effect from the one you are hoping for.
So, remember to STFU, and realize that the whole chewing tobacco thing is just a convenient criticism for her to justify making decisions that have little to do with you and everything to do with her own feelings of dissatisfaction (even if she was actually satisfied in some crucial areas, wink).
