It stinks to always be the grown up, doesn't it? To always take the high road? But, always, do it.
Something I have been telling my 26 yo dd while she has been dealing with her idiot of a father ...and now her idiot of a soon-to-be ex-stepmother. Just keep being the grown-up, sweetie, just be the best big sister to those kids and the heck with the parents. Make a relationship that will stand the test of time with Matt and Nicole and be there in a way that their parents don't seem to get...
but, again, having to be the grown up stinks.
Glad to see your dad came around....don't you stop a thing!!!!
