Her birthday is coming up and it's also right around Valentine's Day. Should I get her something? What do you think?
The very first thing that comes to mind is PLEASE don't give her what I call a guy present. Really, some women are very particular and demanding when it comes to presents and gifts, so if you decide to give her something, make sure it is something that she will value, not something that will perplex her or make her roll her eyes.
That said, I wonder if you could give her a little bit of a hint about it, maybe to gauge where she's standing with the birthday gift thing. She herself may be able to tell you. If that doesn't work or not a possibility, then maybe taking a risk will be the thing to do. If you just risk it, do you think that she will go as far as taking you to a JC? And if that's the case, will you be ok with that? Measure consequences.
One more thing, and this is from my own experience. If you find that she's not cool with the birthday gift, please don't confuse that with her still being "all in". Some JWs and many ex-JWs I know can't care less about anything JW but for some reason they hold on to some of their practices. As I mentioned before, I had an ex-JW roommate who is as gay as I am and did a whole lot of wordly things, yet, he would never accept a birthday gift. The same may be the case with your wife. Even if a person is completely checked out of the WT, there are some things they still choose to keep.
