Is it wrong that I want to make my girlfriend stay in a hotel instead of my apartment?
Why do you want her to stay out of your apartment?
Because my apartment is not suitable for her to stay in.
Don't you think the more reasonable solution would be to make your place suitable? You shouldn't force your SO to stay somewhere else just because you're too lazy to get the place straightened up. Get to cleaning up the bachelor pad, already!
She has to stay somewhere else. I can't stand the smell of her perfume on my couch and underwear in my dirty laundry.
That's not that big of a deal. You should be a good partner and make it work the best you can. It's the right thing to do.
