<human>: My GF is a wonderful person. Pretty, smart and fun to be around. Over the last year our relationship has just become 'comfortable.' We don't really fight, we have date nights, but everything has become somewhat consistent. On top of all this, social pressures of being together for 4 years have begun to add-up and everyone is asking, including her, when we are going to get married? I've told her before how I want to ease into marriage. Let's try living together first, or talking to a marriage councilor. She is admittedly against living together before marriage and doesn't believe in counseling.  I just have doubts that she is the right one, and feel the only way to get past this is to take a step back, and have a break. I've been having these thoughts more and more as of recent, and today I finally brought them up to here and said I think we should take a break.This is my first and only girlfriend, I'm not sure what my next steps should be?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I broke up with my GF of 4 years because I'm afraid she may not be the one. I'm a wreck, now what?
