Karen, Hugs to you. Sorry to hear about his "fragile" state. It really sucks feeling like you have to walk on eggshells to avoid both being over the top as well as underwhelming to the person who is supposed to understand you better than any other. Believe me, I know that feeling well, and I sympathize. MrsGGB hasn't shown the slightest interest in me in over 3 weeks now, and I've given up on initiating any intimacy (kissing included) because the few times I have she's put up roadblocks. Right now, I've pretty much withdrawn myself into work and the kids.
The photos sound hot (don't post them here or you'll have all the guys on here panting too), but I definitely see where you are concerned that they may be a bit over the top given his current state of mind.
You know, I mentioned last month on my thread something about fluency in love languages and how we seem to yearn to have a SO that speaks our LL fluently, and how awkward it is trying to speak their LL when we ourselves barely know how to say hello in it. How much do you think a LL translation problem contributes to your situation? Guess what. Those glamour picts are "I love you" written in your LL, not his. I'm afraid that they'll be misinterpreted as pressure, or at the very least not very appreciated because of this. If you are not careful, it will be easy to take that 'rejection' personally, which may lead to even more resentment on your part. FWIW, I'd love for MrsGGB to do something like that for me, but I also doubt it will ever happen because 1) it isn't her LL and would probably never cross her mind, and 2) she's currently got a fairly poor self-image.
Oh, and the office shark. ick describes that situation perfectly. Try to take his interest as a compliment even though the source is not the ideal source. Imagine instead that it came from the rainbow guy.
