>Does anyone have ideas as to the cause of this?
Yes but I'll be using the assumption that before the GF you were a bit of a loner. I assume this because of where we are + your Pepe posting + the fact you are asking a question about socialising, which implies you still got some learning ahead of you. If I'm wrong I'm wrong.
But if I'm somewhat correct then the cause of the problem becomes clear. It's because you were used to being mostly by yourself for a long time. And being with a other human being for prolonged periods of time makes you uncomfortable because that's not what you are used to. You were familiar with isolation or being on your own. And the way humans work is when you change a familiar habit in a short space of time, the human will respond with anxiety or irritation. Because they lost their sense of familiarity and this new lifestyle feels foreign, weird, forced, fake or even scary.
That's normal. And normal is just another way to say familiar. This shit ain't normal for you yet, but it will be the longer you stick at it. Then the anxiety passes eventually. Then you will notice it becomes your new familiar way of things. And then the opposite effect occurs, you will feel anxiety when she isn't around because then that new familiarity gets changed up. Etc
