I think I'm in love.. Should I ask her to marry me...? (1 problem)...?

i'm the pool boy for this rich couple and one afternoon after long hours of hardwork, I saw the wife, her name is Vanessa btw and she was crying so I talked to her and gave her comfort... then one thing lead to another and we kinda had sex... It was definitely the best i've ever had because she was so experienced and i never felt this way about anyone else... problem is, she's married to a big buff guy who is a trained mma fighter... I want to eliminate him out of the picture so vanessa and i can live happily ever after.... what should i do?
