I might have to disagree with a lot of the posters, your main question on is it possible is YES, you have to fill out a few forms, but she will get an extention to stay in the US.   

While 3 months is not a long time, I know many couples on here have only met their partners once before they get K1 visas, or have only dated long distance, my parents (Both USC) married after 3 months of dating and are together 38 years later, while I have friends who dated for 8 years - got married and divorced within a year.   
 
Who is ANYONE to judge someone else's relationships?!  
 
Work together to find out what is best, do your research and know it is your life, do not let strangers dictate how to have a relationship.  

It sounds like your fiance broke up with you, and you still chose to come to the country and wanted to sue him for breaking up with you?   That is not a thing.  Engagement is not a legal status of relationship.   
 
You can apply for child support, but then he has the right to get a DNA test to prove if the kid is his.  You will still not be able to stay in America, regardless of that.  The baby will be a US citizen but it still will not give you the right to stay here.  
 
I would book a ticket home, and call it a day. 
 
Are the Adoptive parents going to adopt YOUR baby?!  Is that what you mean?

Visa Journey needs a sticky post that just says "Cheating does not equal fraud" and "Taking away a greencard and uprooting your ex should not be your first instinct to a breakup". 

I was in treatment for cancer when we were applying for a CR-1, but it was not in my opinion a reason for expedition.  
 
I believe "Humanitarian reasons" is for more of a spouse who is in a country that is at war, or being threatened.   Not really for the person to come to the US for surgery. 
 
Heck, they even grilled my husband on him potentially being a financial burden to the state for his medical costs.  (Even though he was insured in America, and from Denmark, who has free healthcare)
