Many times we can think of reasons why we cannot directly tell our spouse that they are not currently welcome in the home. Fact is that we may well have no legal footing for trying to keep them out.
That doesn't mean you cannot refrain from inviting them in.
I think when I need to draw back emotionally, I simply make an effort to NOT do anything that would invite the person in. I may not be able to stop them from coming in on their own accord, but by not inviting, by not offering dinner, by not offering a rest on the couch, I would at least feel that I was sending the message that I do NOT want them there right now.
And I think it's important that we explain why, particularly if we have had a different policy before they became involved with another.
It's disrespectful. And I do not believe that disrespectful behavior should be rewarded or encouraged in any way.
Does that make sense?
