I had a relationship with a married man, but suddenly he broke up. Was it real love

Hello sir, I’m isha, DOB 21 Nov 1994, 5:10 PM, Jaipur. I was in a secret relationship with a married man (DOB 9 April 1981). He said he’d leave his wife but suddenly cut off all ties. I’m heartbroken. Why did I fall so deeply for someone so unavailable?
