<human>: My boyfriend of 2 years is the most wonderful guy in the world so thoughtful caring and loyal. I can tell him anything and be myself around him. He fixes things around our house and is so sweet to our dog. 

He suffers from bi polar and it really makes him depressed. Video games have always been an escape for him and make him extremely happy. The problem is, he does it to excess. He usually plays 6 hours a night sometimes more. When I go out of town hell play them for 12 hours a day. He has a job that he excels at so it's not hurting his life or anything. When he plays them it's really hard to talk to him because he has headphones on. I mostly just keep myself entertained on my computer. I think this is really excessive. 

How do I tell him to play less even though its the thing he really loves? Or am I overreacting?

Summarize the given text in a few sentences.
<bot>: my bf plays anywhere from 4-8 hours of video games every night. How do I get him to lessen it even though video games make him so happy?
