I had a lovely mother in law and still adore my sisters and brothers in law, but they all live far away. When I was remarrying, I told me husband a major concern for me was his closeness with his family. They are all still very involved in each others life, and talk almost daily on the phone. They visit all the time. My in-laws have a cabin next to our home they have as a second home. I wasn’t sure if I was ready for such involvement. Fortunately, I came to realize they do respect boundaries, but you’re definitely correct that it’s a whole package, and you better like it or you’re up the creek.
