You have spoken the words of so many wives/gf world wide that have a significant other that plays video games... I too feel lost, alone and forgotten when my husband plays -

If is as though he is in his own little world and refuses to come out for even a little hi or chat with his supposedly beloved wife. I too play (as do my sons) but I find that I can leave the game when I am needed where as the men in my life act of though it is a matter of life or death... and they will die if they talk or pause the game during play.
