There are some unknowns here. The woman put the pictures up in 2010, 5 years after the divorce. They may have been taken soon after the divorce and only posted recently for some reason.
However, as it states that the t-shirt was purchased by the current boyfriend bought the t-shirt in 2009, they can only have been posted a minimum of 4 years after the divorce.
I have to ask, why she (and the boyfriend) felt it necessary to post these pictures on a public website, 4 years after the divorce? It sounds like she has moved on and found a new partner. Why he feels the need to highlight the fact that the ex-husband is an arsehole, is beyond me.
Perhaps the new boyfriend is getting his jollies provoking the ex-husband for some reason, or perhaps the ex-wife hasn't finished tormenting the ex-husband yet even though she's in a relationship with another man.
Not sure why the ex-husband is getting a hard time on this forum.
