Rivka wanted to create a division that would set her two sons eternally
apart. Rivka understood that Yaakov could never dwell in the same
environment with his evil brother, and saw an opportunity to set the stage
for their ultimate separation.
There was always the slim chance that Eisav would walk away with the
berachot. Perhaps he would have repented from his evil ways and won
Yitzchak’s favor.
Foreseeing the distress that Yitzchak would have had at smelling Eisav’s
‘gourmet’ meal, Rivka sent Yaakov in to avert suffering from his
righteous father. His absence from the study hall of the Beit Hamidrash
was really in order to save Yitzchak from distress.
Yaakov went to Charan with Yitzchak’s blessing. His father’s command
to find a wife only reinforced the berachot that Yaakov furtively received.

“Rivka then took her older son Eisav’s clean
garments which were with her in the house, and
clothed Yaakov her young son”

(Bereishit 27:15)
