Why am I nervous around my girlfriend?

It could be because you're worried about being judged by her. If you're constantly worried you're going to do something she doesn't like, you feel like you could lose her. But of course that's not true. If she really truly cares about you, the little quirks won't matter to her. She'd be one to keep around.

Probably because you really like her and are scared of messing things up, but don't be! Girls love it when guys are all cute and nervous! Plus chances are you have no reason to feel this way anyway besides the fact that you really like her.

You can be nervous for a number of reasons, it could be simply because you like them so much, or it could be for another reason that you don't want to mess up around her

This is normal :) It means that you don't want to screw up around her. You care what she thinks I you so much.

Are you sure you're not having any stress or depression? But I am really sure, you're nervous because you really like her.

Well, there are few people we let close to know us on a basic level -- and even fewer we allow even closer to know who we are as people intimately. Things not even someone living in the same house as us would necessarily know about us. And then, there's more at stake- because, you /want/ your girlfriend to like you .. and to continue to like you.

People are nervous in all types of different situations for all types of different reasons. So it could be a lot of different things. Maybe you just want to impress her, and it's putting some pressure on you? A lot of people feel the pressure to make these situations perfect but in reality they don't have to be. When the pressure to make things perfect begins disturbing your life you could have an anxiety disorder and may need to do more to try and control it, like using coping skills, talking to a listener here, or even seeking professional help for starters. It's possible your anxiety is coming from something else as well, but it would help more to know your situation to know what might be causing it exactly.

There's various of reasons. Did you do something wrong that you know she'd disapprove? Did you suspect something she did? Ultimately, talk to your partner to resolve your nervousness.

You might have some issues being your humble self around her in order to impress her. But remember that she loves you just the way you are.

It's not an abstract feeling to feel around someone that means the most to you. If it bothers you that much, maybe you can consult with her that you're feeling this way and talk it out, no matter how embarrassing it may be, it's always good to get it off the chest and have good communication.
