Trying to use dual mosfet to control an SPDT switch. I’m stuck, please help

Hi, I am trying to control an RF SPDT switch which has two control voltage pins V1 and V2. The truth table for the SPDT is attached. Now what I want to achieve is controlling the opposite voltages (0v and -5V) using two p-channel mosfets to deliver these voltages. The gate of the mosfets will be connected to an output pin of a microcontroller which has a voltage of 5V at logic level 1. I was able to set up such a circuit in a simulator however only with positive voltages. Once I make it -5V it all becomes a bit counter-intuitive for me.

If i set the voltage sources to -5V then the mosfets never turn off obiously, no matter what i set my logic to because:
Logic0 (0V gate): 0-(-5) = 5V= Vgs
Logic1 (5V gate): 5-(-5) = 10V Vgs

How would I tackle this issue? any help in the right direction is very helpful. thank you

It may be possible to use an opto isolator, otherwise you normally have to use a comparator or a two stage discrete level switch. What RF switch are you using?
