Boyfriend of 2 years left me for another girl

Abby

My boyfriend of two years left me three weeks ago for another girl. They started dating a week after we broke up. I’m still really lost, I thought he loved me and that he would just need time to think and come back. He kept telling me he couldn’t get over me and he didn’t know if he made the right decision but today he told me I needed to stop talking to him and to never talk to the girl he was dating because she “felt bad”. I’m not sure what to do he’s been in my life every single day for two years and I feel horrible. I miss him so much and I still love him but he’s moved on.
