Woman anxious to avoid making the same mistakes

Dear Abby: My boyfriend, “Aaron,” and I have been together almost 10 years. We are both divorced from narcissistic spouses. We have discussed a future together and are working toward it. It’s taking so long because Aaron’s children are quite a bit younger than mine. (I’m an empty nester; his kids are just going into their teens.) I am also working on getting my career established.
