Betraying someones trust repeatedly is a sign of a serious personality flaw. Barring major life-altering events, personality generally doesn't change very much in adulthood. One of the most common themes in the relationships forum is "How can I get him/her to change?" The reality is, no one can change anyone except themselves.

You have a choice to make: Accept that she is going to be unfaithful at times, or end the relationship. The question you need to be asking here is "Am I willing to deal with this for the rest of my life?"
