<human>: Can you condense the text into three sentences or less?

I need some advice so I thought I would post it here...

I have a friend (F26) whom just got married in January to one of my best friends. Long story short, she wants to go hiking/camping in the mountains west of where I live. Her SO is on deployment currently. I don't share any feelings with my best friends with her that I do with my current girl friend. I love to go hiking and so does my best friend's wife. 

My girl friend (26F) doesn't want me to go out into the woods with just her. She says its very inappropriate, and is very insecure about the situation. I've only been dating her for three months. She thinks I have feeling for her, but in reality she is just a good friend of mine. 

Is this at a point where I have to choose her over my friends? I just want to be happy and have a good time. Advice would be greatly appreciated!!
