I'm not sure I'm following your comment? The only "poor" choice we (me and STBX) made was not buying the TS via resale. 3 years ago we could afford the payments and made them on time with no issue, as a married couple. Due to some situations and poor financial management decisions on his part, there is hardly any money left over at the end of the month (I count about $53.00 between the both of us) to make the payment. So I've been making late payments, or trying to put things on my credit card temporarily so that the things that are vital to me and my son (commuting, groceries, gas, his school payments, and my mortgage) are taken care of. But I can't keep this up, not for the sake of "making memories." Memories shouldn't run someone who is encountering an actual, legitimate life/finance change into the ground.
That is a big poor choice to make. A lot of us have made those same choices. Even buying a timeshare resale can be a mistake but a lot smaller.
There is nothing wrong with you defaulting but do not not expect Wyndham to help you. It is their choice.
