You are doing well....I will always suggest daily review of Sandi's list....it is one of the best resources on this site. Really a window into the world of a WAW.
On moving out....I like your stance and one I followed. There is no reason for you to move out unless a court says so...let it get nasty by your wife's actions. That is just a hole she is digging. As far her continually bringing it up...I will make a response suggestion "I am sorry to hear that you are intent on separating the household. If you are so intent on this course of action maybe you should find an apartment for yourself?"
On the pictures...I would say nothing at this point. I would hold on to them and share the information with your lawyer including dates, etc. I think NY is a no-fault state so it won't help in court. The one thing I would do is research the guy...from his picture there should be enough info to track him down. Do an internet search on the JPG name or number....a know your enemy before you move tactic. I wouldn't be surprised to find out he is a married high school classmate of your wife...and you could use that to your advantage. Other wise what they talk about and do online....don't concern yourself with it. You now know something is going on and that is all you need to know...everything else is just useless pain for you.
Exercising is awesome...pure awesome. I don't mean the walk either (which is plain good for you) but I mean exercising to pure exhaustion. IT will clear your mind, the endorphins make your feel better, and it is easier to sleep. So while I do like the walking, pump it up with something that will kill yourself. I mean doing it right to the point of making yourself sick. That is the type of exercise that will help and you will be surprised how losing a quick 20 pounds and adding a bunch of muscles changes how the world and yourself see you.
