No friends

Sometimes I literally feel so alone. I have my fiancé and he's amazing, truly my best friend. But I have almost zero girl friends. In high school had like 2-3 friends. After graduation we all went completely different roads in life. It's like I almost don't know two of them anymore. And one I text often, but she doesn't make much effort to actually see me or hang out. In college I talk to people in classes, but don't really meet them outside of that, even to study or anything. I feel like such a loaner now. Anyone else the same? Anyone want to talk?
