<human>: Give me the gist of the text in a nutshell

We have a little bit of an independent relationship and do not ever plan to marry or have children. I did believe we were going to form a household someday, early in our relationship there were mentions of it. 

I went house hunting with a friend and learned how much property value has increased in my girlfriend's neighborhood recently. I suggested she move in with me and rent her house out. It'd be a lot of extra cash to have fun with. 

This is when she told me no, we can afford to live alone so she doesn't plan on sharing living space with me for more than a weekend at a time because I'm too messy and she's "not your mother" and even if I tried to keep tidy I'd just end up resenting her for it. I might not care when it's just me but I wouldn't expect her to clean up after me. She also very uncharitably implied that we mostly stay at my place and I had suggested she move in with me instead of vice versa so I could have the upper hand in any disagreements about living arrangements. 

She dismissed the idea without really considering it and basically told me we do best when we have our own space to retreat to and that I should stop counting her eggs (??).

I feel like this means she's not serious in her commitment to me. She's basically ensuring she's ready to cut and run on the relationship at the drop of the hat. We live very close but I didn't expect to be popping in on my girlfriend for the rest of my life.
<bot>: girlfriend thinks we shouldn't cohabit ate. Ever. Is that a reasonable opinion to have in a romantic relationship? Aren't people supposed to want to live together?
