Hi Cathie & WELCOME to SA.com! You've landed in a great place for help, so add it to your Favorites and keep coming back here.
So sorry to hear that your marriage is dissolving! I don't have any specific advice that I can think of at the moment but if it twere me I'd probably try to refinance at 30 years and then try to pay off ASAP. The 30 year smaller payment ought to give you more breathing room in the day to day budget. No way to just keep the existing mortgage by having your soon-to-be-ex doing a quit-claim??
I also might try to find a financial advisor.
You might want to check out the SAblogs too - there was someone??? can't remember who right now, maybe it was CarolinaBound, who posted in one of the contest about what she wished she knew before her divorce? If memory serves, Broken Arrow is one of the bloggers as well, who posted about his divorce thoughts.
On moving on? I just found this in the SA forum archives (which I heartily recommend):
Squirell and the acorns
Step by step you'll get there! Like eating the proverbial elephant, one bite at a time! And, congratulations, it sounds like you are already pretty financially savvy and w/o CC debt you'll likely make the transition easier than those who are up to their eyeballs in debt.
