Yes, stick to the plan. Don't let it drag on past his bedtime though. You don't have to slam the door on her a$$ to make her feel shut out. She will feel it just by being separated from the son and all the niceties of home. It is important to not swing from one extreme to the other. Don't go from pansy to vindictive. Remember, you are interested in reconciling. As a good friend once told me, "burn only rotten bridges."
