Colin Charvis' agent has blamed Neath-Swansea for the breakdown in contract talks.
Colin Charvis may have to look abroad for an employer
Negotiations between the Wales backrow and the regional side broke down last week.
But Peter Underhill told BBC Wales that Charvis was prepared to compromise over what Neath-Swansea director Roger Blyth said was "financial and other terms".
That offer was rejected by Neath-Swansea who, according to Underhill, were unwilling to enter further into talks.
"We had negotiations with the Neath-Swansea set-up last week where I believed we had come to a mutually viable agreement," Underhill said.
"Then on Friday we had a 'phone call saying Neath-Swansea had withdrawn their offer for Colin.
"We had another meeting on Monday and Colin was prepared to compromise, but Neath-Swansea weren't prepared to discuss it."
Underhill revealed that there have been other offers from outside Wales, most notably from English and French clubs, but maintained that Charvis was "100% committed" to regional rugby in Wales and the Test arena.
However, Underhill did admit that the most lucrative contracts on offer were for players who were prepared to abandon the international arena.
Wales coach Steve Hansen is on record as saying that he would have no problem selecting Charvis if he signed outside Wales, but the player is still waiting to hear on the Welsh Rugby Union's stance.
With Charvis' contract apparently too rich for, or rosters having already been filled by, Wales' five regional sides, there has been suggestions that a central contract with the WRU might be a compromise.
But chief executive David Moffett is unlikely to go down the route that brought rugby league star Iestyn Harris to union in Wales, with the WRU still deeply in debt.
That leaves Charvis with little choice but to accept a wage below his expectations, or move abroad.
"He is absolutely devastated and I think Colin feels slightly let down," Underhill added.
"The last thing he wants is upheaval and to move away from where he lives and what he believes in.
"But circumstances sometimes dictate that sometimes happens."
