After living together for 2 years, my girlfriend abandoned me, but when I was ready to get married,

How long ago was it, if there should have been no time limit for litigation within half a year.

Ask a lawyer, they know and will give you the right answer, good luck.

What are you suing her? She didn't break the law, she was free in love, and everyone was equal. Marriage is a relationship that is established on the basis of equality and voluntariness of both parties.

Did she take your money? If there is, you can sue her for fraud, and if not, what do you sue her? Do you have the bottom of your own heart? Is there enough evidence? However, unmarried cohabitation is not protected by law.

What did you do earlier? It's late! Admit it.

You haven't registered your marriage, and the law doesn't protect that.
