I'm wondering if we now have enough information to figure out the actual timeline of this whole mess

I don't know exactly when some of the following happened (episode dates are different than real dates) and I'm sure some of the things in my list can be disputed, but most of this is from information in these threads:
2008 - when? - Jon starts sleeping in the basement of the old house
Oct 2008 -- when Jon said the marriage fell apart
2008 -- they move into the
new house but Jon moves into the apartment over the garage
2008 -- Jon starts going to counselling -- he says Kate refused to go (we have no evidence of this -- maybe she went to her own) -- he continues to go by himself
Jan 2009 -- the family goes to Utah, Kate goes home early without Jon
mid-February 2009: pictures surface from Shorty's bar in Pennsylvania. Jon was staying with his mother for several days ... there were also rumors coming out of Juniata College that Jon was at a house party there.
May 2009 -- Jon is staying at Hailey's parents' home, he said the marriage was over
June 2009 -- TLC does the special episode re the divorce (but we don't know when that decision was made)
June 2009 -- Kate files for divorce, stating she had to to protect her children from Jon
June 2009 -- Jon starts publicly dating Hailey (yes, it's disputed when this began but this is what they stated and nobody has come out with info to the contrary) -- at this point, no matter what had occurred before, I'd say the damage to the marriage was irreparable.
I left out the Deanna stuff because the only person that says they were dating was Deanna's useless and creepy brother, plus that happened so long after what I considered the relevant info ie. they were already doomed at that point, JMHO. Or maybe I'm missing the relevance of him going out to bars -- was this really a new thing that started in spring 2009?
Please everybody, feel free to edit, add, change -- I think together we can figure this out or at the very least come up with a few possible scenarios.
