OP don't listen to anyone else on here.
You might not be as social as her. There's nothing wrong with that. It could be an incompatibility long term but keep reading
You need to have your own circle of friends. Only need 2 friends minimum. Just some other guys to BS with, meet for a drink/coffee once in awhile. If its an activity/hiking friend thats great too.
If she ever leaves, yeah it will suck but you won't be at 0.
Also, develop a strong interest in something outside of work. Not video games
