His mum and dad love me. We’ve been togerher almost 2 years. However his younger sister who’s younger than me doesn’t like me. Maybe she has reasons as we’ve broken up before and had big rows in front of her. When I’m around her I do not disrespect her. When I’m at their house she sometimes makes me feel uncomfortable. I feel like he don’t have my back he’s only once shouted at her for being rude.
What should I do?
who are introverts?
