Polyamory

How long did it take you to get to compersion for your partners on your poly journies? Was it always there? Is it different each time? Any insights on say, experience, time, and compersion in general??

As I'm moving through what has become on ONGOING relationship for my husband (his side girlfriend) and dealing with the myriad of emotions that seem to be ebbing and flowing through it, I am maybe just looking to read some experiences that might help me as I patiently live through the non-compersion I have now, in the hope that it will eventually develop.
