Dear Dave,

I’m getting married this summer and about to become a stepmother. To be honest, I’m a little worried about the family dynamic. My fiancé’s daughter from an earlier marriage seems a bit irresponsible. She’s 23, has trouble holding a job and still lives at home. She seems to expect her dad to step in when she does not have money for her car payment. We both agree he has been too lenient with her in the past. He wants to change things, but neither of us believe suddenly pulling the rug out from under her is a good idea. Do you have any advice for handling this situation?

— Susie

Dear Susie,

If you and her dad really want to show her you love her, you’ll make sure she starts learning some character and discipline. It’ll take a little time at this point, and it’s very important that both of you are in agreement every step of the way.

Marriage counsellors say you have a good chance of a successful marriage if you’re in agreement on four things — religion, money, children and in-laws.

I know you and your fiancé love each other, but I’d strongly suggest you two go through pre-marital counselling to make sure you’re on the same page when it comes to handling this and other issues.

After that, I’d recommend letting her dad present any changes to her initially. Neither of you wants to create a scenario where you’re viewed as a villain. Let her dad start the process by explaining that he feels he made a few mistakes in terms of teaching her personal responsibility when she was younger. Then, he can begin to lay out the first few expectations.

In my opinion, there’s nothing wrong with requiring her to get a job within 30 days, if she does not already have one. If she needs to go job hunting, the process should be an everyday thing, because if she’s unemployed, finding work needs to be her job — her full-time job. It would also be a good time to start teaching her about budgeting, saving and everything else that goes into handling money responsibly.

Phase two might consist of requiring her to help around the house doing chores, or whenever help is needed. After a couple of months of this, phase three might be where she is introduced to the practice of paying a very small amount in rent each month.

Do you see what I’m doing, Susie? By stepping up expectations gradually, you’re building a foundation so she’ll have the tools and knowledge to where, in the sixth or seventh month, she’s able to move out and live like a fully-functioning adult should.

God bless you all!
