Hi guys!

We are in our early 20s, work at the same place. I would do anything for her if she asks me for help and i ask for nothing, nor credit needed for me, just to know that she is happy at the end. Yesterday for the first time, she helped me out with my project, and today when our boss walked out to our meeting room, she showed him our project and what she has done and took credits for that. . After that my boss looked down on me, like i'm not doing my project on my own. My girlfriend asked me to forgive her for doing so. And even days before, she was telling everyone that she will be late at work with me, and everyone were teasing her, like "hey pretty, you working so hard" she likes to hear that, i know that and there is no problem with that. Why did she did that to me? Personally, i would have never done this to to her under to circumstances

Is that common to be with such girl? Situation like that already happened before like couple of times. Just what bothers me, is that does she truly loves me if she does such things? I don't care about boss or project, but her love.

I didn't ask her to help, she just got very interested in that project and asked whether she can join me just to for curiousity reasons
