I have been with this girl a little over a year now. She loves me and has always been there for me, it's not that I am not attracted to her. I just know that I still have time to find other people. I guess the problem is that she is 5 years older than me (im 21 she is almost 27.) She has brought up getting married and that kinda shit but stays away from mostly because she knows that I am not ready for it. I also have to make plans to hang out with my buddies or go drinking or whatever like 2 weeks in advance or she gets all shitty. I just want to be able to do what I want when I want. How should I go about it?
