Breaching a promise of marriage and fake love

No case of cheating is made out in given circumstances. So forget the matter. 

Hello, 

Sir, 

This is a common problem these days. 

However, if you wish to proceed legally, there are a variety of options. 

Please connect with me through OLQ to discuss about the same. 

Also, please do note that you should have concrete evidences for the following; 

– False promise to marry 

– Cheating 

Dear Sir, 

You can file a civil suit for damages for:

Mental agony,

Emotional trauma,

Reputation loss, or

Monetary loss (if she took advantage of your trust).

But note: this is difficult to prove, and you will need solid evidence like messages, chats, or witnesses showing she misled you intentionally.
