I started university last September and I became very close to two of my flat mates. The latter took a few weeks to join us so I bonded lots with the first one. We were SUPER close and clicked so well, like we literally made each other laugh constantly and we were literally inseperable always with each other. Then the new one came a few weeks later and we soon bonded with her too, so we became a group of three best friends. We went everywhere together, helped each other and were always there for each other, made each other laugh all of the time etc. The other two did the same course and I did a different course but apart from that we were with each other practically every minute.Then in December it's time to start arranging student houses for next year. Usually close friends live with each other. I ask them if we should get a place, they both say that they want to live on their own separately. So I have nowhere to go. One day I'm walking through the corridor and I hear one of them on the phone saying that she's going to live in a house with the other one, together.I was so shocked, and quite hurt. I asked the other one if it was true, she said that they had been thinking about it for a while. I didn't get why they had lied and left me out, when there's a group of 3 very close friends you all live together (usually up to 6 people live in student houses). I'm not dirty at all, I clean and tidy my room everyday and clean the kitchen regularly, wash my dishes etc. so I couldn't understand why they would leave me out. I felt like they had pretended to like me all this time.After that I stopped speaking to them, I never angrily confronted them. Am I right to feel hurt and angry? Who is in the wrong?
