what is love

so, im 20 and in my first relationship with this amazing and wonderful guy, we tell that we like each other and the other one is so special and stuff, its been 7 months and my bf just told me he LOVES me.... my problem is that i cant feel the same, and im so scared i will never actually love anyone, also im confused if i am in love or not, never in my life i have loved a person and i honestly believe i never will, i dont even love myself to begin with, sometimes i really feel i cant create a deep connection with somebody else bc everything will end up wrong and i dont want to get hurt?? idk im so confused im gonna cry
