I had noticed a change in her texts for about 2 weeks. It was subtle but she stopped with the lovey dovey names to me, stopped saying I’ll be home and just in general less excited. EVERY thing else stayed the same. She cooked, laundry, talking in person, sex was amazing, no bitchiness/fighting.
So you were living together even though you'd only been dating a year? Or was she just spending a lot of time at your place and calling it "home"?
As for the "no other man" - I wouldn't be so sure. She could be communicating with an ex-boyfriend on FB and you'd never know, right?
Was the vacation recent? If so, maybe she was waiting until after the vacation, or maybe the vacation clarified her thinking?
Now - if her request for "more space" was accompanied by some actionable complaints: you drink too much, she's tired of cooking and doing laundry for you, or other such things - then maybe it's as simple as that. If it's really because she's "used to men leaving" - she may not be someone who can be happy with a stable relationship, because there's not enough of the DRAMA that she grew up with and associates with "true love".
Any which way - unless there's something she made clear to you that YOU were doing that was a problem (and not stupid excuses like walked too heavy or paid someone else $30 to do the yard) - you're probably better off moving on. Who wants to be with someone who is second guessing their choice this early on? I want to be with someone who thinks they're lucky to have me.
