Gf broke up with me because I wasn’t doing enough.

I don’t use Reddit but figured I would get your advice. I 28M was dating this wonderful girl for a while 29F. She was exactly what I wanted at the time. Smart, loving, charismatic and kind. In the beginning I will admit I was chasing her and going above and beyond. After a while things started to fizzle down and that original chase was no longer there. I admit that I started to date her less, and stopped complimenting her as often. I loved her but I just did not see the point in doing the things I was before. Which I know makes me sound like a asshole. Long story short she gave me a few chances to get my shit together and told me she missed who I was when I was chasing her and trying to make things official. I took her for granted and she left yesterday. She broke up with me while at our favorite bar. I have been a mess since then. I did not think she would leave the relationship or leave me. Fellas please learn from me, remind your girlfriends that you love them and appreciate that they are in your life. My arrogance got the best of me, I do not think I will ever find a girl like her again. I know we have a tendency as men to think there might be better out there, but that’s bullcrap. This girl and I shared everything together, our goals and hopes for the future. We where talking about moving to South Carolina in the next few years and starting a family. It is going to be impossible to find someone that loves me like she loved me. Her love for me was unconditional and I feel like a piece of shit for treating her like I did. How do I get her back? Can I get her back!???
