My husband is addicted to video games... HELP

Jessica • Mommy of two. Audrey Kathleen 1.5.15 & Our Angel Baby 9.19.15. Never in my arms but forever in my heart.
My husband is 24 he works M-F 7-3. We have an 18 month old daughter. I work from home so I am able to keep our daughter with me during the day. He gets home at 3:30. Eats and immediately hides away in "his room" this is the room that has the computer and Xbox. He will stay in there until close to midnight if not longer. He hardly ever helps out around the house. he never helps with our daughter he has changed maybe 15 diapers in the year and a half sense we had her. He has never given her a bath and it's like pulling teeth to get him to stay home with her while I run to the store or something. It is really starting to piss me off that he is so self centered! For a while we tried a schedule where he could only play from 3-6 (I get off at 6) Tuesday and Thursday and he had Friday and Saturday nights to play as long as he wants because God forbid we actually do something on the weekend that might interrupt his gaming. HE EVEN TURNS DOWN SEX if he's gaming. I don't know what else to do! Please help!!
