Add another link between R2 and R3, either physical or a tunnel
interface. Add an additional route on R2 and R3 for 10.10.10.0/24
pointing out this interface so they have two equal cost routes installed
for 10.10.10.0/24, one out the link to the other neighbor (R2/R3), and
one out the Frame Relay PVCs. Lastly configure policy routing on R2 and
R3 so that all traffic received in the link to each other (the new
interface you added) is sent out to R1. Your per-destination or
per-packet load balancing on R2 and R3 will then take care of sending
some traffic to R1 and some traffic to the other router (R2/R3).

Can you just use GLBP and be done with it?
