I'm dating a guy for 6 months now ( my longest relationship believe me) but now I had this job thing and I had to move to another town for a month. He is visiting me time to time but it's killing me. Any tips !?

Their is this guy I dated for 6 months he loves me and I do too but then I had to leave for one year for a job and we are now keeping a long distance relationship. We obviously talk day and night but it's killing me and I'm sort of panicking and thinking what if I haven't met him I don't know anything anymore help!!!
