Going to Russia wasn’t far enough away from her. But his letters to her when he needed her help to get back to the USA sure were “nice.”
Yes, he turned his back on her and the family when he first arrived. Told Robert to go to hell. Then when he needed them it was suddenly a different matter.
He abandoned his family for the USSR but wanted them back later when he needed them. Then he was willing to abandon Marina when he tried to kill Walker. But wanted her back when he failed. Then he was willing, again, to abandon them when he tried to defect to Cuba. But wanted her back when he was rejected.
Finally, he abandoned them once and for all on November 22, 1963. Giving them $170. And his wedding ring. Swell guy, just swell.
