You really need to set up boundaries. You also need to evaluate yourself: ask yourself what are the expectations you have in others? What crosses the line? Do you yourself meet these expectations? What would you think/say to a peer if they were encountering the same situation(s)? What are the advantages? Of course the big litmus litmus test is would you be proud of your choices down the road? Could you ever discuss this with a future partner or even child?

Also, what messages would you say you are conveying? Is this something I am encouraging?
