There Is A Curse Laid On My Family

We will begin with the backstory of this alleged curse:

My Italian great grandmother who lived in Italy was once married to my great grandfather. My great grandfather had children and a good life with his Italian wife. At one point, he left Italy for something that I believe he told his wife had to do with business. When he left the country, he met another woman, my family calls her Mema, who would soon become his other wife. He loved Mema more than he loved his Italian wife, even though he had a life already built back in Italy with his Italian wife. His Italian wife had somehow discovered that he had another wife and another life outside of living in Italy with her and their children. That made her very, very upset and angry. It has always been said that in her extreme ire and anguish toward his actions, she had (intentionally is unknown) placed a curse upon his family and all those who descend from him and his other wife; my immediate family now.

So, jump to today:

I feel that the Italian wife cursed all Love relationships in my family. The signs: nobody in my family has a happy love relationship; every member has some sort of repeating turmoil in any relationship they get involved in, including myself. I've had a number of men that I've begun to have a thing with and all of a sudden they all just drop me with no warning. Same for my mother. Another less relevant sign but I still believe it has some significance is the fact that all men in my family had daughters and all women in my family had sons, except for my grandmother and my late grandfather, son of the cheating Italian great grandfather and the other wife, Mema, who had sons and daughters together.

Peculiar thing about Mema: before she died, my mother was the last to see her. My mother was up in FL where Mema lived and was visiting her for the summer. Mema told my mother to get on a plane and go back home to NY because she had a feeling that something bad was going to happen soon. Mema was a Medium, she could sense future events and could communicate with spirits, such as my mother can, as well. My mother complied with her Mema and got on a plane and returned home to NY. Mema had been complaining of it smelling like gasoline in the garage as well when my mother was still staying there. Shortly after my mother boarded the plane, Mema was doing laundry, which my mother had done a countless number of times at her house during her stay there WITH the gasoline leak having happened already (but did not die from), and apparently some leaked gas from the car parked on a rug in Mema's garage where the washer & dryer were had caught flame once the spark ignited from either the washer or dryer. The ignition of the gas exploded Mema's whole house, killing her. I now believe that it was the Italian wife who had not only cursed the entire family, but also played a big spiritual role in Mema's death. I believe that the Italian wife had become so jealous and enraged about her husband cheating on her and marrying another woman while still staying married to her with their children that she caused Mema's death somehow. It's just not logical that the gas leak would ignite when Mema was doing the laundry but not when my mother was doing the laundry, even though Mema had been complaining of it smelling like gas when my mother had been doing the laundry prior to this, yet after the gas had already leaked.

I need to know what I can do to break this curse upon my family! I am desperate because this is affecting us all very deeply, but I am the only one who really has any desire to deal with it. I want to make good for my family and myself, but I need guidance in doing so!
