If I understand correctly you are trying to do an interlock between two relays. This is a well known problem which is solved by a trick in connecting the relays.

You have the circuit for energizing relay 1. In thinthis circuit you put in series onone of the inverted output contacts of relay 2 which are not the "main" output contacts, just a low voltage "additional" contact. If relay 2 is energizesenergized the circuit to energize relay 1 will be open due to the open contact of relay 2. And also vice versa, in the circuit which energizes relay 2 you connect in series an inverted output of relay 1closed. 

The same way, ifcircuit energising relay 1 is energized, this breakswill consist of +5V in series with the additional contact of energizing relay 2.

What you need is 2 relays, which do not simply havethe coil of relay 1 connection to energize themin series and 1 connection which is open or closed, but also offer "monitoring connections" which can be normally open or normally closed.

Relays for industrial automation offer such capabilities. Electronics relays might not.

If your relays do not offer such option, you will have to add logic gates or more relays to make these inverted contacts. If not, you can always buy a board that already does this, like this oneground.
