Husband's gaming is ruining (has ruined) our marriage.

I'm new here and don't see too many posts from significant others. I just don't know where else to go.

He was recently diagnosed with depression and his constant gaming isn't helping. For years I've asked him nicely to come do things with me, but he just won't. The games were always a priority. Before we had our son, it didn't bother me as much because I figured if he enjoyed gaming, let him. But, we have a kid now and he is STILL spending just as much time at the computer, if not more.

I'm heartbroken for my son, myself and my husband because he's missing out on so much!

I guess I just need some advice.
