The main issue she worried about was our kids. The case is that at school, they fill in blanks about family, and there it is mentioned if parents are married or not. Therefore, she decided to explain kids the situation in their family telling the whole truth. And you know, they understood.
Another advantage is that they try to make such situation bring romantic shades in their life.
All in all, such family satisfies them perfectly well, and in the near future they're not going to change anything.
