You need to investigate the possibility of OM in her life. Keep an eye on cell and bank records. This advice to "not snoop" is misguided and very dangerous. Until you know exactly what you are dealing with, you need to "snoop" to protect your own well being and to be able to head off any of her shenanigans. As far as her "getting angry"....so what? Let her!! Do not operate out of fear. Keep your cool no matter what she says or does. She will "get angry" about anything and everything. Again, so what? Women do not respect a man they can boss around; it is very repugnant to us and reeks of weakness; not at all attractive. Stand up for yourself and let her anger roll off your back.
