I don't know about Jesus, but the comment about man being given a wife made out of his side (the hebew could mean either side or rib), does indicate that a man and wife is the ideal. (the flesh is one). However, the bible also has plenty of examples where men had multiple wives. The ideal is not a commandment in genesis.
I personally prefer the translation of 'SIDE' instead of 'RIB', because it indicates an equality (side by side) in a marriage, rather than a woman being in a subserviant role.
