<human>: We've been dating 10 months without any serious problems or a genuine fight. I recently moved out of my parents' house and into my own apartment. He still lives with his parents and his expenses primarily just concern fast food and child support (~$300/mo) while working around 35-38hrs/wk for $10/hr. He does not pay for rent, utilities, babysitting, or groceries at his parent's house. Generally, we split/rotate the costs when we want to go out.

But he's practically been living at my apartment. I don't mind him being there 5-6 days a week, but the man likes his long showers and hot baths, and he uses more electricity than I would (he doesn't work until afternoons, so he's there after me in the mornings, usually up later than me watching Netflix). Right now, I've just been asking him to buy breakfast-related groceries, to which over a month he made a purchase of a gallon of milk, a bag of bagels, cream cheese, eggs, and an avocado. He hasn't offered to pay for these things, but hasn't objected when I asked him to.

I just get my monthly bills and think, these could probably be halved if he wasn't here all the time. I wouldn't think of charging him rent, but I feel weird asking him to pay because (1) he lives here but doesn't *live* here, and (2) I don't have a standpoint from where to say, "This is how much I paid before you." Am I being cheap/out of line to ask him to pay for, say, breakfast groceries + 1/3 of my water and power bill? Is that too much, too little, just right? Neither of us have lived on our own before, so this is new.

I'm probably over-thinking this.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: My boyfriend is at my apartment 5-6 nights a week, likes long showers and late night movies, is it uncool if I ask him to contribute to a portion of the utilities/groceries?
