So I’ve been with my boyfriend of 5 years, and lately he’s been disrespectful. He’s been speaking to me so rudely. Telling me to shit the fuck up & he doesn’t want to hear it when I simply just try to talk to him. I use to drink a lot and he told me to change so I did and I’ve change the way I’ve act with him. But he doesn’t admit his flaws and his excuse for everyone is “well that’s the way I am, before I met you” I’ve been trying to change the relationship for the better so we can grow and learn from it so I’ve been trying to communicate better but he never wants to talk, he ignore me, walks away, or just yells at me and I can’t take it anymore or don’t know what to do.
