You have the darnedest way of sticking in my mind. I love the fact that you'd want to know in a positive manner a significant other of your former spouse's in the interest of the children. Mutual 'friction-free' relationships help make life easier for your daughters. I'm trying to implement the same type of thinking with ex and Mrs. ex if and when the time ever comes.
Things sound like they're falling in place for you.. the day job, your boyfriend (...manfriend?). You just get more and more incredible.
