Can you sue an ex girlfriend for a broken promise of marriage?

First of all, sorry to hear about your break up.

Depending on the state or province you live in, civil courts/small claims will accommodate the opportunity for you to investigate whether you can sue for financial loss or damages ensued from the break up. Infidelity and bruised ego can't be used against her, simply because you were not married yet. If you're serious, spend an hour paying for a lawyer and see what your chances are.

ANSWER:

If we sue people that hurt us, we will be rich by now. My husband will get rich if he sue me, and I will be a millioner if I sue my husband, his ex mistress, and his family for wrong doing. When someone promise you something, try not to believe on that person, so at the end you will not be hurt. I know.....
