@Patrick batemens wife so how is she "stealing" boyfriends? Why are you talking like she is the bad one? If a guy has a girlfriend and likes her, why would he even look at that girl trying to "steal" him? In any case, if you have a crush on a guy just get close to him, if he likes you back he wouldn't accept that girl advances (if there are any), and if they date well he didn't like you enough not to put his eyes on other girl 
In any case, the person dating was not that girl. She is not the best because she put her eyes on taken guys, but the ones cheating or changing their girlfriends were the guys, not that Sherya girl, so she isn't the real villain. If the guys left their girlfriends to date her, they didn't like their girlfriends at all and Sherya actually made them a favor by taking the guys away, if it wasn't her it would be another girl, but those guys would've cheat or left anyways
