<human>: My boyfriend and I have been dating for a year and a half, and for the most part, it's a lovely relationship. However, in the past few months he has been acting rather immaturely. He has to wake up early for school/work, yet he stays up til 4 or 5 AM playing games and watching TV, and he often eats only one small meal a day, even though there is plenty of free food available at his house (his reasoning for this is that he's bored of certain food items, or doesn't feel like cooking). 

I wouldn't be getting upset about this though if it didn't happen so often and he didn't whine about it constantly. I don't want to control his life, and I wouldn't care if these things only occurred infrequently; we're college students, who don't always have money for healthy meals or time for hours of sleep. However, when I hang out with him, he spends a great deal of time moaning about being exhausted/hungry, and he has so little energy that our dates are becoming lackluster. Instead of going out and having fun, all he does now is sit around complaining about how tired or hungry he is.

Lately, I feel more like his mother than his girlfriend, constantly trying to get him to eat a few decent meals each day and sleep more than four hours a night. All of his causes of complaint are completely preventable, but he never seems interested in acting like a responsible adult. And spending so much time offering sympathy to his easily avoidable problems is wearing me down. I'm also becoming quite worried about his health, he's going to collapse if he keeps going like this.

How can I get him to listen to my concerns? And how can I discuss this with him without seeming like I'm nagging or being bossy? I recognize that it sounds silly for my boyfriend's eating/sleeping habits to become an issue in our relationship; does it seem irrational for me to have a problem with this? Any advice would be greatly appreciated.

Can you give me the gist of the text in a nutshell?
<bot>: My boyfriend spends all his time lately complaining about the consequences of his own actions, and it's starting to become rather annoying.
