Just not right...

Alright so tonight was the first night in probably 2 weeks that I've gone home to my flat since I had been staying with my girlfriend. My friend Rich comes over and him, my flatmate Owen and I decide to play some video games. We decide to play Call of Duty Modern Warfare 2 which is an awesome game. Now tonight, even though this is like the 4th time I've played this (twice on Special Ops and twice on versus, both versus I got destroyed) I completely rocked the game taking down my friends quite well. Since I was doing so well, I decide to show how happy I was by saying I was playing it and playing it awesomely against Owen who owns the game and has played it significantly more than I or Rich have combined, by mentioning it on my Facebook status. Now that was 3 hours ago, and 3 hours more of gaming later, I come back on here. I look at what's happened on Facebook and apparently my GF has joined a Facebook group called I hate COD which is for GF and wives whose 'other halves' play the game too much. That was 2 hours ago that she joined, 1 hour after I mentioned I was playing it. Now does that seem fair? We haven't been together that long for one (1 month tomorrow) and since we've been together I've played it 4 times and twice with Owen. So i don't understand how she could think I play it too much. I mean c'mon, in the past month we've been together, I've been home like 5 times for a night each. I just don't think that's a fair judgment on her part. I beleive it may be in spite as we had a small argument earlier and though I got over it, she hasn't. Oh well. I just needed to say that because I thought it was quite funny. All I know though is that it's just not right.
