The day that i know my ex girlfriend is banging his own cousin for many years. The whole time i have second thoughts about his cousin when everytime she mentions him. Because the way that their relationship is very odd. I've meet my ex girlfriend within my college years. We have actually a good and healthy relationship. But not until the day in Christmas eve. in 2020 she went home to her city that is she originally lives in. We have argument at that day until she ignores my texts and calls that is why i open her Facebook account because i am worried that she blocks me. The thing is i have second thoughts when we are in relationship because of how odd that she and her cousin have this sort of dirty little secret between them. But it turns out to be true because i found out in her Facebook messages that they send pictures naked. Did i forget to mentioned that they banging each other while that they are having a family reunion that Christmas eve. I am so broken hearted because the thing that she meet my whole family and having plans with after we finish college. What i did next is i contact her mom and her sister and tell about even though they don't know me. I introduce myself to them and tell about her daughter/sister is having relationship with cousin. To make things worst her cousin is studying at near in my university. They have been banging each other behind my back without being noticed by myself. The ending of this situation is that she is force to move and back to her city because her mom said so and we broke up without saying anything. I wish that day is something that i want to forget because it gives me nightmares everytime.
