The thing is, you're trying to juggle too many things.

Even in your example, the lines are always between two objects, it so happens that one of the object interacts with two different ones.

Simply handle it differently: first handle the horizontal line, then handle the vertical line.

if (tops of rectangles line up): draw a line on the top that connects the corners if (left of rectangles line up): draw a line on the left that connects the corners if (right of rectangles line up): draw a line on the right that connects the corners if (bottom of rectangles line up): draw a line on the bottom that connects the corners
