I met a girl at a mall, hit on her, got her number, during this process I jokingly called her the love of my life, the joke was repeated a few times between the both of us. A few days later we went out, things escalated quickly and I ended up loosing my virginity to her, during sex the "love of my life" joke began being taken seriously, we had a good time and a few I love yous' were exchanged. Now she says she's counting the hours till' our next date in a way that makes me think she loves me, I'm uncomfortable with this.
How would you advise I proceed? Preferably remaining fuck buddies, not bf and gf.
