Well this is an old post by cake but it describes a very similar situation that I found myself in a few months ago. However, I am on the other side- the boyfriend trying to deal with the girlfriend's indiscretions. Cake's boyfriend seems a lot like me. If I found out for sure that my girlfriend was cheating on me then she would be done- it's just too much to get over. What Cake needs to ask herself is not why she cheated because that can't be changed, but she needs to ask how am I going to change and stick to it. You have one account at the Fidelity Bank and Trust and once it's closed it stays closed forever. However, that's not to say that over time you can't walk back in those doors. Right now, Cake has no integrity. It must be built back up slowly, each day that goes by without cheating is another brick. Telling the boyfriend is a risky move. If he found out and Cake hadn't told him then it's over for sure, however, if there is little to no threat of that happening then I would say file the cheating actions away like you would an old photograph. Cake should only do this if the integrity stays intact, otherwise she is never going to change and he deserves someone better..
