His remark came at a meeting at his official residence to discuss holding a party anniversary function in Ratnapura.
No hasty decision is needed since there are five months left, he noted, adding that their support was needed to take that decision.
When the president asked for their views, they replied that a decision should be taken very soon.
W.D.J. Seneviratne said they would leave the government after the agreement ended in September, but would support the president whenever necessary.
Mistakes of the government should be rectified, he said.
Their’ remaining in the government, pursuant to a SLFP central committee decision, has created a big problem for the party and supporters at the village level are finding a major issue in it, he said.
If this continues, the SLFP will find it very difficult to win future elections, said Seneviratne.
Nimal Lansa said the SLFP would have to accept blame for every wrong of the government.
Supporters want them to leave the government, he said, warning it would be very disadvantageous for the party if it did not.
People are rallying round Mahinda and Gotabhaya Rajapaksa, and a carefully thought out decision has to be taken, Dilan Perera said.
The president will get an opportunity to take a decision, when the Central Bank bond scam fraudsters are revealed, he said.
Mahinda Amaraweera, S.B. Dissanayake, Sarath Amunugama and Mahinda Samaraweera said they should take a collective decision, without giving into the joint opposition’s machinations.
Doors are open for anyone to leave, and the government should continue with those whose who remain, Amunugama added.
