Yes. Why are you in a rush? Even though the boys like him... let them have time to adjust their feelings about building a new family. If you can afford to not move in just wait. If you have known him for 1 1/2 years allow the boys some more time with him and him more time with them. Allow them to go through the Wow Pow and Reality of a new relationship. That is to say... wow-he is different than Dad and that is cool. Pow-the first time he does something or several somethings that they don't really care for. Reality-regardless of the yucky stuff I have seen, I am ok with him-he is a keeper.
