Here again is another serious red flag reflected in your fiance's behavior. Your fiance has at least emotionally cheated on you (at least this is all you know) by seeking out other men on Craigslist and when you raise legitimate, reasonable alarm about how serious this is, SHE 'holds it against you' when you want to call off the engagement. I don't think she 'gets it', perhaps? If this level of unwise and immature judgment dooms your relationship eventually, you are probably count myself fortunate that you have a good sense of her. Also, I wouldn't blink an eye about her parents getting upset about spending several thousand dollars on deposits. I hope your fiance has the courage and maturity to come clean with them and explain that you called off the wedding because for the third time, she was messing around with other guys on Craigslist, and was emotionally cheating on you. Were I her parent, I'd count you as a wise man and her, as an immature, foolish woman who isn't ready for a real marriage yet. I would be glad to have not spent even more money on a wedding, for a marriage that wouldn't last unless my daughter got some quality help and 'grew up' quite a bit. So if they become angry or put out by this, it means their daughter hasn't told them the truth about what happened, or if she did
, and they are still mad at you, it could be that you don't want to marry into this quality of in-laws.
I hope your wise, objective and rational thinking rules your decisions regarding this relationship. As I suggested, you can test where her head is at regarding her desire to be fully transparent, open and honest with you anytime---now, in 2-3 months, etc., by asking her for full sharing and disclosure of internet accounts, passwords, bills, etc. If she passes the test, great; it means she is maturing and you are probably getting on the same page regarding the true meaning of loyalty and monogamy.
