Jess, Diane’s math is good! As you know, when you get divorced you cut your lifestyle resources in half. But you still have 100% of the care-taking responsibilities. It’s good you are being realistic about this situation, and there is no shame in this.
Mike had a bonded pair of green wings for 15 years, and then we got a bonded pair of Hyacinths. The green wings had two clutches of chicks and we hand-raised two of them until they were 9 months old. As much as we loved them all, when Mike was diagnosed with cancer (he’s fine now), something had to give. Birds can be wonderful pets, but they are extremely needy, messy, and loud. We also spent an incredible amount of money just feeding and caring for them. It was hard, but we re-homed them all, and they are all with loving families who can give them the time and attention we could not. Since their lifespan is so long, they will be with their new families longer than they ever were with us. And we gave them a good start in their lives.
Whatever you decide, make sure you are putting yourself first. If you burn yourself out, you and all five of your pets will suffer. If you decide to re-home them, you are providing an opportunity for another loving family to have the joy you’ve come to know with them.
Bless you as you approach another fork in the road.
