Romania sealed their place in Division-A earlier in the evening meaning that victory for Britain would also have seen them remain in Europe’s top league.
Yet, despite three of Britain’s players hitting double figures - Sarah McKay with 15 points, Rosalee Mason 11 and Lisa Hutchinson 10 -they were unable to secure the much needed win.
Head coach Mark Clark said: “Maybe the pressure of the game got to us.
"We knew they would zone us and we were more than adequately prepared.
“We had enough chances in the first half to win the game and the way we started the game I fully expected us to finish plays better.
"It’s disappointing because we were in control but just couldn’t score when we needed to.
“We always knew playing this number of games in such a short time would be a factor and we were a very tired team today.
“I expect us to win in Bosnia but to do so in Romania will need one hell of a performance.
"This team doesn’t want to be a B-Division team.”
Britain now travel to Sarajevo to take on an already relegated Bosnia on Friday before they head to Romania to play the group winners.
Victory in both countries is a must if Britain are to keep their hopes of staying in Division-A alive.
Britain’s 6ft 7in centre McKay had not played since their opening game in Finland, which the team had won, but she returned to the squad posting a double double which included ten defensive rebounds.
She said: “It’s heartbreaking.
"At the end we gave it to them.
"We had every opportunity to put it away but we just couldn’t do it.
"We have two big games left now and we need to learn from our mistakes.
“Hopefully we can improve and get better.
"They normally shoot a lot of threes but tonight they happened to make a lot of them.
“Neither team shot pretty well but they started their game up well.
"We gave them too many second chances.
“I think we can bounce back.
"It will be hard but we need to stay together now.
"Bosnia will be hard and they will be our first focus.
"We are going to two places which won’t be very welcoming.”
