So bf and I have been dating 6 years, we have been sleeping over at each other’s houses for a few years now. He has a brother who is a narcissist lair, he guilt trips my bf and is toxic in our relationship. A few years ago for Christmas when my parents were coming to meet my bf family for the first time his brother literally said he doesn’t want strangers in the house and was spreading rumours about my family which wasn’t even the truth. His mom told him to stay out of it and he didn’t he then proceeded to lie more and make my bf turn against me ON CHRISTMAS that left me in tears. After being through all that I still forgive him, a month ago he tripped off as usual and tries to make my bf sound like he is insane when my bf speaks the truth to the parents about what’s happening but yeah he literally came up to my bf and I in our face and told us we aren’t gonna last, not gonna lie that hurts, but I think he is only like that because he is unhappy in his life as he is a fuckboy basically as he brings different girls home every week and after Friday nights clubbing.He would come home and just talk about rich girls he want or he tryna get with. He also talks about the amount of money these girls family has. My family thinks he is just jealous of me as I’m the only child to both parents and we are well off. Anyways what’s y’all thoughts on this and what advice would you give with dealing with the situation?
