The scrum-half is set to leave the club in June and doesn’t know whether he will get to wear the black, green and gold again.
The season is currently on hold due to the Covid-19 pandemic that has swept the globe.
On March 16, the Gallagher Premiership was postponed for five weeks, but it looks increasingly unlikely that it will resume any time soon.
And Reinach does not want the 16-10 win at Worcester Warriors last month to be his last as a Saints player.
“I hope we can play again because you don’t want to end the season without knowing it’s your last game,” Reinach said.
“We did win the last one, which is good, but I try not to think about it being the end.
“Hopefully we get back to playing again and the boys are training hard enough to get back quick. Let’s just hope it’s not the end.”
Reinach has made 76 appearances for Saints since switching to the club from the Sharks during the summer of 2017.
He was named players’ and supporters’ player of the year last season after a stellar campaign that saw him score 17 tries in just 30 games.
And he added: “I don’t want to end it this way, even though we won.
“There is an emotional build-up to playing your last game for the club and to saying goodbye to everyone.
“At the moment it’s just a stop and pause and hopefully we can continue.
“I hope it’s not the way we’re ending it.
“It is emotional, it’s difficult and I don’t know how to feel about it at this moment in time.”
Though it has yet to be confirmed, Reinach’s next club looks set to be to Top 14 giants Montpellier.
And the South Africa star, who won the World Cup with his country last year, has already been having to make arrangements for his move.
“Boys leaving and ending contracts have to carry on with organising their stuff to where they’re going and getting their house in order,” Reinach said.
“But the season is not over yet, it’s in a pause mode and hopefully we can continue.
“We do have a little bit of time to sort things out and we don’t have to think about too much rugby, but once we get the go ahead it’s all rugby again.”
