living together is a compromise
when i first moved in with my ex GF (we were together for 3 1/2 years) i was addicted to CS and it did cause problems because of the amount of QUALITY time i missed out with her.
Yes i understand you see her all the time, but that isn't the same as spending time with her, and trust me i completely understand with the watching pointless crappy shows and not wanting to.
For us, our problem lied in the fact that when we moved in together i felt it was a necessary financial step as roommates etc however she felt it was a step up in our relationship. Thats were the difference lied, and you need to compromise on time spending.
You see she might not just be watching those shows as you like to play CSS, to kill time and have a little fun...she might be watching them in an attempt to spend time with you, just don't know exactly what else could be done. You really need to communicate about it too, ask her what about it she doesn't like and what she doesn't mind.
You'll be able to work out a schedule where you guys can actually spend quality time together every day and have your gaming time.
Personally i think the worst advice is to play when she has gone to sleep...that was the biggest annoyance of my GF at the time. When she goes to sleep, you should be going with her. Its a great time to lay down and talk for a little bit or whatever else you want to do. Never go to bed angry, seriously.
This is a compromise remember....so maybe she needs to give up some of her shows in order for you two to actually do something together that you will both enjoy, and maybe you'll need to give up some gaming time. However they can co-exist, so work on it and communicate about it...you shouldn't necessarily be asking us, but ask her.
