She cheated now what?

I agree, if she really loves you that much then she needs to go talk to a psychologist or counselor. People that send s, or modeling photos, or anything like that to others is looking for security in their looks. She probably thinks that she is unattractive and so she sends s to others to reure herself that she is pretty. She has a self-image problem and you cant really help her directly. You can only be there to support her in giving up this addiction. Tell her to either talk to a psychologist or something. Or ask her what she wants to do about the problem. I would suppose this is no different than a b/f or g/f having an addiction to drugs, alcohol, , etc. You have to find something else to occupy her mind. Start telling her shes beautiful more often to get her mind outta that place, or have her send the s to some cell phone that you own (but that you do not intend on viewing or w/e if its illegal pics) so that she gets it out of her system. You gotta be careful with things like addiction. Things you say or do towards an addicts' addiction can turn ugly quickly because they dont want people to know they are addicted. This is why she argues with you to the death over a lie. She is ashamed of the addiction and doesnt want you to know. Just be careful with what you do. If you make a mistake in helping her it could scar her for life.
