A while ago my cousin who I have always been close to moved to my neighbourhood so she started spending time with me and my friends. To cut a long story short she slept with one of my friend’s partners. I think it is relevant that she was very drunk and quite naïve and he is incredibly sleazy. After it happened he pursued my cousin but she told him to leave her alone and that it was a mistake. He has come onto me and a couple of other women in the group in the past and has a history of cheating on my friend. We all hate him but my friend loves him for reasons I can’t fathom and is still with him.
My cousin doesn’t spend time with that friendship group anymore for obvious reasons but I am still close to her. My friend recently blew up at me as she saw a facebook photograph of me and my cousin at a family wedding. My friend seems to think I should disown my cousin while supporting her relationship. My friend also went a step further by contacting my mum on facebook to let my family know what my cousin had done. Luckily my mum has no interest in her niece’s sex life and ignored the message.
I would like advice on how to handle the situation. I understand that my friend is hurting but there is no way I am going to disown my cousin and I am really angry that she is trying to stir up trouble in my family. I also don’t see how she can expect me to be OK with her sleazy boyfriend yet cut-out my own flesh and blood.
