<human>: We started our story back in 2010, actually I started the story by writing a letter to her in 2010.. my family moved to another country before I know her reaction/feelings about what I wrote.. after one year we came back home and we met, she told me that we are young for all this love-thing.. so I accepted her opinion and forgot about her.. one week later she changed her mind and she said that she loves me back
We keep traveling every year for my father's work conditions, and my girl and I could only meet each other for one month every year.. of course the long distance decreases both of our feelings.
For the past two years I went back home to study there so we've met a lot.. and we talked a lot. 
Several times she brought up the age problem as a not serious topic or a joke.. but one time she was serious about it.. she said: I know your mind is bigger than your age.. but I still see you as a child.. ( It damn hurts, because I think feelings is the only thing that matters in love). 
The age problem is even more serious recently because she is finishing her 1st year in college, and I will start college after 3 months.. she met the guys there and she formed some good relationships with both genders, I'm ok with that, but in this April I traveled with my family, and for the first time we start texting on What's-app, so I noticed she is not engaging that much in our conversation.. she gives short answers, she doesn't bring new topics "when she can" also she rarely expresses her love for me
I started to think she lost her interest on me.. because I'm not really attractive, the age is a turn off to her.. and the distance is making it even worse. So I asked her one time: If we go back in time.. would you fall in love with me again?" .. she said: "No.. It had nothing to do with you, but the circumstances"..... now you judge

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Maybe you view it as an obvious situation, but I'm really confused.. and it's hard to lose her because I really love her.
