How long should you "wait for someone" if they say that they need time to think about things (when in a relationship)?

For those of you who have read my posts, you’ll know that my girlfriend and I are on a hiatus (I’m a girl, as well). Anyhow, she is telling me that she cares for me a whole bunch, but, due to various circumstances (things that had happened the last time that we were together), she needs to think about what had went on and that she’s still a ‘bit catious’ about getting back together.

I respect the fact that she needs a bit of time (so far a couple of weeks), but, and not to sound insensitive here; how long would a person need to figure out whether they would want to be in a relationship or not? I’m doing my very best to patient, but, it’s killing me. I love her a lot and it’s hard sitting by and not knowing what’s to come.

When I asked her a week ago if she wants to ‘let go and for both of us to try to move on’, she said that she still wants to think about things in regards to us being in a relationship. Anyways, this is tough. I’ve apologized, told her that I loved her so many times since and told her that I’ll wait for her. Ugh!

Any advice?
