Welcome.
It's sounds like you want a relationship, and not like a one time threesome thing.
Though it might be easiest to imagine as "Just like before, only adding a third!" it might be worthwhile to rethink it. Emotionally it might feel more like "We are breaking up on purpose to start a new relationship model with a new partner or partners." So don't be caught off guard if after the initial "Whee! This is exciting!" NRE stuff wears off, you maybe face some sadness and don't know where it came from. Poly has a way of shining a light on things.
I get the idea of sharing a new GF seems exciting, but it also makes your dating opportunities slimmer in an already smaller dating pool. Basically you are asking
Are you up for poly?
If so... are you up for poly dating both of us? Like a triad, one of the hardest models because it's 3 V"s stacked up together?
If so... are you up for doing all that when we are brand new to polyamory in general?
That's a tall order.
Before jumping into poly dating and seeking a new partner, you might consider reading the pitfalls to help you stay out of common mistakes.
Might also think about the work of detangling.

Pandemic makes things a little tougher, but check in your area for poly munches or meetups that are doing their gatherings online during COVID. Not as much to start dating, but to start learning. Since online is online, might also check out other munches or meetups in other areas for now, and then when you get closer to dating focus more locally.
It is not uncommon for a couple to take a year or more in preparation.
It is also not uncommon for a couple to just jump in underprepared, and make a mess.
You get to pick how you want to navigate this.
Not trying to be a wet blanket... Just sayin' tread with caution.
HTH!
