Frequently asked questions

Why is my sister-in-law so manipulative?

She loves to get her own way and will use any means necessary to do so. She’s very persuasive, often using emotional manipulation or guilt-tripping in order to get what she wants. She also loves to control the situation, often dictating how things should be done or how conversations should go.

This can be really frustrating for those around her, as it takes away their autonomy and makes them feel like they have no say in the matter. 

I think the reason why she is so manipulative is because of a lack of trust. She feels that if she gives up control then people will take advantage of her, which is why she clings on so tightly to whatever power she has.

Signs of a controlling sister-in-law.

A controlling sister-in-law can be difficult to deal with and can make family gatherings or holidays a challenge.

Do you find sister-in-law is always trying to get involved in everything you and your spouse do? It is understandable that she wants to feel included but it’s important for you to have your own space too.

Try explaining this to her, but if she still insists on tagging along with you whenever possible this can be frustrating. 

Come up with creative solutions such as suggesting activities that involve all three of you or setting aside special days when it’s just the two of you doing something together. It’s a delicate balance but by compromising and communicating clearly, you should be able to keep everyone happy.
