Was Gautama Buddha's wife Yesodhara in any way instrumental in Him becoming a Buddha?

Considering the story we know about the life of Buddha as Siddhartha and also considering that Yesodhara was Buddha's partner in His many previous lives, can we say that Yesodhara was somehow instrumental in Siddhartha becoming a Buddha? OR With or without Her being in His life He would have made it? (Her pervious life with Buddha is in wiki article and here .) *I know this question is as such irrelevant to practice but I am trying to get around this idea called '**soul-mates**' which is in pop-media.*
