<human>: My BF and I met online thru videogaming. I consider myself a heavy gamer but I work full-time and play less than 3 hours a day (even during my day-offs)

My BF on the otherhand... he'd play upwards of 10 hours a day. From the moment he turns on his PC at 9am till he has to go to bed at 1am, he only leaves his PC when he has to shit or eat. 

This didn't bother me so much at the early stage of our relationship. We live apart. I felt like I had no say in what he does in his spare time. We see each other once a month. Lately, there has been talks of moving in together in 2016. If my BF lived with me and this is all he did, it would certainly be a problem. I just don't know how to bring it up.

Another aspect about this whole thing is his weight gain. He has gained A LOT of weight since we first met. His figure does not bother me. I still find him attractive, but a lot less than when we started. He complains about his weight gain. He has moments where he goes super emo about his weight and the fact that he doesn't do anything about it. The thing is, I agree with him. He does absolutely fuck all. Then comes whining to me about it. I've gotten to the point where I don't care anymore. I've tried encouraging him to exercise (he has a bike) but he is full of excuses. I've encouraged him to use MyFitnessPal (which I have been using religious for a while) and again, more excuses not to.

He sounds pretty content at the lifestyle he has. I don't even know if I have any power to make him see that this is super unhealthy. He has NO OTHER HOBBIES and NO FRIENDS.

Provide a brief overview of the text.
<bot>: BF playing 7+ hours of videogaming everyday and getting fat. Whines and whines but does absolutely ZERO. Getting fed up and starting to lose interest in considering him a life partner.
