HELP pls!"太太"现在和福建老头一起,是外卖店老板娘

他们"同居"5年(不知二人婚姻状态),今天电话找到了她,请求离婚.她却害怕对我朋友承认是我"太太",否认认识"自己". 我确认是她,只希望她可和我快正式离婚,照今天她否认自己的态度,我不知道她会不会接受我的申请,我已等她6年,最近真相大白后,直想快快结束.

我已应我的好朋友,他们愿意帮我交涉离婚,我也保证不会去和他们有任何联系,或是任何接触,以避免不必要的言语冲突.

但我似乎看不到前景,如国朋友的调停失败,我或不得已用一些法律保护自己.

请问法律高手,不得已时,我的胜诉几率?
married in china,no child, no property,I can prove we separated for 6 yrs(she used to be F-2, don't know her current visa status or marriage status),
3 yrs ago, she ever send me e-mail from a stranger's account to tell me we could divorce in china, then never reply or contact me for divorce. So in our 7's marriage, she just told me one time in e-mail: we could divorce, then never showed up.
