Christ, dude. I don't know if that's something to be proud of. I never understood why people get married a bunch of times.
Judge not. If you haven't been there, you can't understand.
On Topic...OP, your only option is to explain to your SO why gaming is good for you. In my circumstance, I have a highly stressful position with a new company and it does me a world of good to come home after a 10-14 hour day and unwind with a good game. If I don't have that distraction, I don't unwind because my thoughts are still focused on how to develop and improve the company.
For me, gaming is (almost) a necessity. [Anyone can use that excuse if they feel the need, I hold no copyright or trademark]
