I'm not going to pretend that Efim was a saint. We've all seen some of the things he did. But if he did break it off with her, then I glad for him. With the way he used to gravitate towards other women and him being as young as he was, he very clearly was not ready to be in a relationship. And with the way she used to throw tantrums, hit herself when she got upset and/or cry at the drop of a hat, he very clearly did not need to be in a relationship with her (calling her unbalanced is the perfect adjective). Like I said, they both need to sort through some shit. Efim needs to fuck a bunch more women before even thinking about getting serious with anyone else and she needs to work through her issues.
