I'm just catching up on what happened today. That totally sucks.
IMHO, the presence of an OW shouldn't change your DBing- you can't mention it (I thought ITH was spot on), so it really is another of those situations when you need to take a breath and act as if everything's OK. Every time you mention the OW, it makes the WAS leap to their defence and their feelings become more entrenched.
You're totally right that you've got a better job, and are hotter than she is (I know- I've seen you ), and have the positive history. it'll take her years to build that up, and a much shorter time for him to lose any negative associations he might have. So you're in a better position than she is. Plus you have integrity and morals.
In relation to the work banter/camaraderie, H had that with the aubergine too. Is there anything else you can banter with him about though? Amusing musical clips on YouTube as T uses or something similar? I'm sure there must be some funny clips about buses somewhere
Hope the outfit trying on is going well. I think hot pants and thigh high boots might have some kind of effect on H, although possibly not work compatible!!
