Love Means Healthy Boundaries

Why do we need boundaries and do we need them with everyone?  What does a toxic relationship look like?  Communication is Key!! How do we mindfully communicate with others?  Why is it hard to set boundaries?  Do expectations of us happen because of our roles (i.e. wife and mother)?  Do we allow co-dependence or lack of "self preservation" to happen to us?  How do we maintain a balance between what we value and appropriate giving to others?
