Dear Annie: I’ve made the decision to distance myself from my sister, who exhibits narcissistic, dramatic, needy and demanding behavior.

For years, I offered her help, advice and support, only to have the relationship follow a repetitive and unhealthy cycle. I would set boundaries and shut her out after being hurt but eventually let her back into my life.

Unfortunately, she simply cannot respect my boundaries. She would be kind and polite when she wanted something, but her response would quickly turn into anger, abuse and manipulation when things didn’t go her way.

After enduring years of emotional manipulation, constant demands and hurtful accusations, I finally chose to prioritize my own well-being. Her lies, theft and damaging behavior became too much to bear.

Although I love my sister and miss the good times we shared, I can no longer tolerate her toxic behavior. It’s a difficult decision, but ultimately, it’s what’s healthiest for me.

Have others experienced similar situations with family members, and how have they coped with the decision to walk away? Did I make the right decision? — Estranged Sibling

Dear Estranged Sibling: It sounds like you’ve done everything you could to maintain a relationship with your sister, but unfortunately, she hasn’t been able to respect your boundaries.

Prioritizing your well-being is important, and it seems like stepping away was the right choice for you at this time.

That said, don’t forget that people can change. It might be worth checking in with her periodically to see if her behavior has shifted and if the relationship can be rekindled in a healthier way. Wishing you the best as you navigate this challenging situation.
