He have a site two connections from same MPLS provider on a router.  They are operating on two different VRFs. How can we bridge the two connections so that going forward we only one physical connection, but two logical connections?

Create another VRF and add those VRF's into the single VRF. Make sure you have routing in place as well.

Ask  you provider to deliver both MPSL VPNs on a single dot1q trunk. This may include a re-provisioning process with your provider. Typically providers will deliver MPLS circuits via dot1q, did you ask them not to? Do they have Ethernet? If so, on the local router, create sub-interfaces for each VRF/VLAN/DOT1Q vlan-id on your local router. You will need to configure two bgp sessions, one for each VPN. You can aggregate them into the a single routing table (global) or you can create two seperate VRFs to maintain segmentation.

We are checking with teh provider, they of the opinion that the two MPLS networks are domestic and Intl.
Both are provided over Ethernet. I would let you know if they are not able to combine connectivity.
