So I initially signed to live in a group of 8 in second year, but the group kicked me and my friend out because my friend was being problematic and they didn't want to live with her. She and I signed for a two-bedroom house because we were running out of time to find a house and we didn't have many other options at that point.
Over the last 3 or 4 months, I've started to understand why the initial group didn't want to live with this person in the first place. She is *****y, gossips about people, causes drama, and treats her friends poorly. I'm sad that I didn't realise this earlier and was forced into the position of signing for a house with her. She ditched me for a boyfriend and barely makes an effort to ask me how I am anymore, mostly only speaking to me when she has a problem. She always tries to one-up me in the sense of putting a dampener on me when I'm in a good mood; for example, if I've been out with another group, she'd say 'Oh, I'd hate going there', or if I've started a new activity that I enjoy, she'd say 'I wouldn't like that, it's boring'. She always draws the conversation back to herself.
She and I joined a new friend group after the previous group kicked her out. I love them and I think they're great people. However, they've noticed the difficult parts of her personality, particularly her tendency to gossip, and don't want to see her anymore. She has no idea. I'm still friends with them and they've said I'm welcome to come to their house whenever and go out with them in second year. I'm happy about that.
The tricky thing is the living situation with this girl next year. I really can't see myself being happy living with her, particularly because it's just me and her. I just don't have any other options.
I'm thinking of giving her a call over the summer to speak about her behaviour, in the hope that she'll reflect upon it and behave better in second year. I just don't know what to do. Any advice?
