It takes time to set boundaries and see parents acknowledge their child is a grown-up. On the other hand, sometimes it's okay if you let your mum indulge you.

This resonates with me. I like to listen to Eckhart Tolle talk about being present in the presence of family members.

How are you working on this? This is an issue in our marriage. My wife struggles to make decisions when her parents are around. I've also struggled with this.
