Should I get back with my gf?

my gf and I broke up on our 1.5 year anniversary. I love the girl and think she's amazing, which makes this even harder. I was the one who said we needed a break. Reason being I couldn't reciprocate the love she gave. I saw how she was blindly in love and would give anything. I wana say I was same for her but I'm not sure. Cause she was my first, and my first long term. We broke up cause we r graduating in a year and it hurt her to know we would go separate ways, she couldn't just let the future be the future. And it hurt me to know that I was hurting her in that way. I couldn't promise a future with her. been two days. I wana get back with her. but it's been a year and a half since I last was single. I feel like a dick but I am kinda looking forward to it. I wana live by myself for a while and focus on being a better person. I wana be able to give as much love as her. .. I know I'm causing my gf to cry, but I can't talk to her for a week I promised myself. I love and miss being with her! is it over? this is the third time we have taken a break, the other ones we got back together. that's why I feel the third time is the charm. time to move on. just kinda sucks knowing I had so many amazing times. And that we r such a big part of eachothers life, and if I decide next week to not be together, than well that's probably the last time I will ever see her. That's hard for me to coupe. We worked well together, knew each other great. But I just feel there's another door waiting
