There's no "maybe" about it :-)
What's this got to do with _ethical_ hacking? (Look up ethical in the dictionary.)

That's a VERY bad idea, even if you can do it. Ask her about your suspicions. Then decide whether or not you believe her. Then decide whether the relationship is viable or not (if you don't believe her then it probably isn't). Then either drop the suspicions or end the relationship.
Have you cheated on her? If so that in itself could mean you're paranoid about her cheating on you. Escpecially if she knows and has forgiven you.
