Life is a series of hellos and good-byes. It is about attaching, connecting, and often separating and then detaching, disconnecting and letting go. In toxic relationships all-too-often one or both participants are not skilled when it comes to limits, boundaries, or letting go. Toxic people get addicted and have issues of neediness that cause them to avoid letting go when a healthier person would run the other way from the sheer emotional pain and suffering alone.
