Hello virginislands: I see this is your first post here on PC. So... welcome to Psych Central.

Perhaps other PC members will have some thoughts they will want to share. From my perspective, though, I think you may need to provide some additional detail with regard to what is occurring for someone to be able to be of help.

In the meantime however here are links to 4 articles, from Psych Central's archives, that talk about how to deal with difficult (or even toxic) family members as well as others plus links to 2 articles on the subject of personal boundaries:

How to Deal with Difficult Family Members

Dealing With Unhealthy Family & Friend Relationships: A Brief How-To

How to Deal with Critical People

What's a Toxic Person & How Do You Deal With One?

An Introduction To Boundaries and Why We Need Them | The Psychology of Self

I hope you find PC to be of benefit.
