The 26-year old winger joined the Steelmen from English League One club Rotherham United in August on an initial agreement which was to expire in January.
However, Ainsworth remained at Fir Park and has scored seven goals in 19 Scottish Premiership outings to help the club to third spot on the table and he is now looking to guide them to a spot in next season's Europa League competition.
"It would be massive. I've never played in Europe so that would be brilliant," he told the Daily Record.
"When I heard about the loan move, I was trying to get here before the European games at the start of this season but I didn't manage that. Now I'm trying to help Motherwell into Europe.
"Getting there and playing there would be a great experience.
"I love playing up here and if I can go and play in other countries, it is all experience.
"We've got guys who have done it and are still doing it. We've got a few internationals in the dressing room.
"I'm a free agent at the end of the season and I'll see what happens.
"But Motherwell have a big place in my heart. I love everything here - the place, the club, everything.
"When I came here I was nervous but the lads were brilliant the way they accepted me and I had to go out and show what I could do. After I got a few niggles out of the way I've gone out and done the job."
