Re: My gal does not sleep at home every night!
Well, you guys aren't really living together, even if she's there every night. It's not your place, and it's even less 'her' place. It's not ideal for you, but I can kind of see where she'd be coming from.
My wife didn't move in with me until we had our own place. When we started dating, I already had a house, lived alone, and had more than enough space. But had she moved in, it wouldn't have felt like 'our' place, let alone hers.
Your current arrangement, it's not even 'your' place, it's somebody else's. If she already has her own place (which may even be shared with somebody else), then that is what feels like home - not living with her boyfriend in your buddy's house.
