Have anybody experience this kinda of situation?

My girlfriend moved into my apartment from NJ to NY. We also have a child together. Ever since my girlfriend moved to NY she said her best friend stop texting her or making an excuse to not hangout. She get mad that her friends hangout with other people. So she feels that it my fault that her best friend stop talking to her. I am like how it is my fault just doesn't make sense. She told me she missed her best friend so much and wanted me to give up my apartment to move closer where her best friends live. I told her your best friend is jealous but she doesn't think so. Her best friend is a single mother have 3 baby daddy. Have anyone have a similar situation?
