<human>: We are college classmates. She broke up with me about a month ago.
She had been giving indications of sort, but never said or talked about it explicitly. I mean no relationship works like clockwork, I just took them as bumps on the road.  
So our semester exams end, and she just calls and drops the hint that its over. I am obviously overflowing with emotions. I ask her to meet to explain/ discuss this (Hoping it can be sorted out).  
She remains adamant. I get the "its not you, its me" speech. She says she needs alone time and doesn't want to be in a relationship.  

So I am introvert and relationships have been far and few for me. So instead of NC, I keep trying to contact her, talk to her, you know try and woo her back or something. Because I am unable to digest her reason.  

Anyway a month of vacation passes, college reopens, and during this time her ignorance has increased very greatly.  
I let it go for a few days, but then I lose it. I push for a talk. She says "she wasn't feeling herself" during the relationship and to her its doesnt feel natural[the relationship].  
Now the thing is except a few bumps here and there I never felt we had a fundamental problem or incompatibility, it was going great. So her point of view looks difficult to digest.  

Some notes:  
1. She used to drink and smoke quite heavily and is a chronic migraine patient. During the relationship I made it clear I didn't condone of it, and she abstained.  
2. I may have been kinda controlling in some ways. I have been an introvert and not used to frequent relationships, so in hindsight I see that I could have over-possessive of sorts.  

Three semesters of college are left, she is in every class of mine. And getting over this is looking almost impossible for me.  
The only thing keeping me going is the hope for rekindling of the relationship. Otherwise I feel like having no purpose.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: GF dumped me. She doesn't feel like being in a relationship. I don't buy it. I feel I may have been over possessive. Overcome with emotions. Want to rekindle relationship.
