<human>: My girlfriend of 4 and a half year just broke up with me and I'm crushed. We met in college and started dating when we were 18 and I thought everything was going great. She was my first serious gf and We never cheated on each other. I felt like I was in the perfect relationship with the perfect girl. Recently it had gotten a little rough because She had moved to another state(about 2 hours away) around 6 months ago for grad school but we still managed to work it out. 

She called me today to break up with me because I wasn't affectionate enough for her and this is something we had dealt with in the past. I know something like this is difficult to change as I've had 4 years to try but still couldn't get it right. I really love her and Still have trouble accepting that I've lost her. I don't really know what to do right now. I know it's my fault and I regret so much but I don't know if there is anything I can do anymore to fix it. I always held her hand and kissed and hugged her just not always to the point where I'm making out with her which is 

We had plans to get married and spend the rest our lives together but I don't know if that is a possibility anymore. I don't know if this is something I can just get over.

Can you summarize the given text in a few sentences?
