Why am I so nervous around my girlfriend?

That is a question that I feel you can only answer for yourself. It's important for you to evaluate it yourself and figured out way.

It's natural to be nervous around your partner, especially if it's a new relationship. Many people experience nerves in romantic relationships as people feel like there is a lot of pressure to be perfect. If you're feeling nervous, talking to your partner about it, chances are they feel the same and so you can help each other through it.

Maybe it is because you don't want to mess up or lose her because you did the wrong thing. You should tell her you are nervous around her and you guys and work out a plan or something to do about it :)

Maybe because you like her so much that you seem anxious about possibly embarrassing yourself in front of her, or upsetting her?

Many reasons. Because you really like her so you don't want to embrace yourself in front of her is one good reason.

because it may be new to you.you don't know whats gonna happen so its nerve raking. I not know if this was helpful but it may be...

Is this your first girlfriend? If so, it could simply be because it's something that you've never experienced before and it all feels a bit odd. This is something that will improve with time, so i wouldn't worry about it :)

That is amcompletely normal feeling, especially if you are at the beginning of your relationship! The reason as to why you are nervous depends on your situation and relationship with your girlfriend. If you just started dating, you may be nervous for any number of reasons! It is a challenging thing to begin and build a solid relationship with another person. It is two separate individuals, coming together, sharing sometimes very intimate things and not knowing how the other person will respond! Even if you have been together for awhile, nervousness can come about with any types of change. For example, if you both are recovering from a major argument, learning/doing something new together, coming together again after long distance, etc. There are also more personal reasons. Do you feel insecure in yourself for any reason? Are you nervous around your girlfriend only or other people as well? Another important question I would consider is what type of "nervous" does she make you feel? Is it a nervous-excitement? Which may be a good feeling, like looking forward to a first date. Or is more a nervous-dread/fear? It is good to think about why you feel this way as both an individual and in your relationship with her. I wish you the best in discovering your answer!

You are probably nervous around your girlfriend, because you like her and you don't want to mess things up. Probably the best thing to do would be to be yourself and be polite.

Maybe you are insecure. Loads of people are, it's nothing weird. Maybe just talk to her about it. That could help.
