As girl pregnant in relationship & boy getting married to another girl

Yes you can prosecute him for the false promise of marriage, Now he is the father of the unborn child and he cant denied his obligation towards his child.
Please try to solve the matter before going to court.

Hi,

In this situation, yes you can perfectly proceed with a police complaint and also complaint under the sections of cheating. However you will need to tread this with caution as you need to decide whether you want to marry a man who is being forced to marry you. However, I also understand your predicament, since you stated that you were together for 11 years, it would grant you the status and inherit the property of your ex spouse even if you were not legally married. The Supreme Court has granted status to unmarried couples who have resided for a number of years together. However this would be determined according to your age and when you got into the relationship and so forth.

11 years is too long and clearly you have been cheated and exploited by false promises. The guy never had the intention to have a future with you. You can file a case for cheating, rape- by giving false promises and by inducing you to have physical relationship. Let me know if you need further assistance

You should file a complaint against him under 190/200 CrPC as he committed to you for marriage due to which you got pregnant and now he is going to marry someone else...................................
