Digitalread; Input pin stuck and weird

Reading values via DPDT relay and pin input. I thought you solved the problem in the project through the last forum. But it's not. It is always either high or not. It is the same when you activate the input pull-up. It sounds like you're sleeping, but it's true. It consists of input via three relays. The first pin can be controlled somehow. But when the second pin goes up, they change to the opposite value at the same time. I tried to understand this, but it's hard to even understand the pattern well. I need your help.

It would help if you posted a schematic. Even a hand drawn would be better then the Frizzy thing.
