Hi OP
I met my husband when we were 23. We didn't move in for a couple of years- I just wasnt ready, he asked me if I wanted to before then and I didnt want to, I was just starting out in my career and liked living next to work and friends and he lived at least a 30 minute drive away.
It worked though because we were both on the same page. We both agreed that we eventually wanted to live together for 6 months then buy a house together somewhere else, we weren't sure whether we wanted kids but thought we might when we had established careers etc. We were both sure what would be happening just not quite sure when.
At 30 though I can see where she is coming from. If she knows for sure she doesnt want children then it's less pressure but even if she isn't sure, a whole extra year to wait for someone who then still wont be sure if they are ready, is cutting out quite a high proportion of the chance she is going to be able to have children (given medical advice is to start before 35). That's quite a big thing you're asking her to do.
To be honest you say you're mad about her, but not mad enough to actually make up your mind (and most people know whether they want a long term relationship with someone within a year) - what do you think is going to change or what are you going to find out about her in the next year that's going to sway your decision one way or the other? You're not desperate to see her after a week apart, you don't enjoy seeing her enough to sacrifice any time on hobbies or friends, you think that she may be unreasonable for asking 'for the next step and the next step' which is what most long term relationships do.
Basically you want to 'date' her long term, but havent told her this. You like your own space, friends, house and hobbies which is fine but if you don't want to change your lifestyle to make room for someone else then maybe you should be clearer with her what you do want.
You want a girlfriend, she wants a future partner. If you dont know if you'll ever be there then just let her go. I've never heard of anyone man or woman who hasn't been sure for a few years and then suddenly decided they did want to settle down with their partner and it's all been fine...
