Dear Annie: I’ve been married to a wonderful man for over 10 years, and during that time, I’ve grown to love his son as my own. My stepson, “Brian,” is now 28 and has struggled with drug addiction for most of his adult life. We’ve helped him through multiple rehab programs, paid his rent when he’s been evicted and even bailed him out of jail once. I’ve held him when he cried, driven him to meetings and prayed for him every night.

But nothing seems to change for long. He always promises he’ll do better, and for a while he does — but then he relapses, and the cycle begins again. He calls at all hours asking for money, sometimes with stories I know aren’t true. I try to set boundaries, but the guilt eats at me. What if this time he really is in danger? What if something happens to him and I wasn’t there to help?

My husband is worn down, too, but he’s better at pulling back emotionally. I still see the little boy in Brian — the one who just wants to be loved. I know I can’t fix him, but the idea of cutting him off feels like giving up on someone I love. — Hurting Stepmom

Dear Hurting Stepmom: Loving someone does not mean enabling them. You have gone above and beyond, but addiction is a battle Brian must choose to fight. Giving him money, rescuing him from consequences and staying on call 24/7 is not helping. It is keeping him stuck with a disease.

Set firm and loving boundaries. Let him know you will support his recovery, not his addiction. This is not giving up. It is giving him the best chance to stand on his own.

And do not do this alone. Seek support for yourself through Al Anon or a counselor who understands addiction. You need strength, too.
