<human>: Reddit I need your advice!! I'll try and keep it short and simple. 

basically my girlfriend broke up with me 3 days ago over text and I was really taken aback. her reasons: her new semester at school has her extraordinarily busy and her school schedule and my work schedule (she's 20 in college, I'm 23 and I work full time) do not mix. she feels she can not dedicate enough time to having a boyfriend while balancing school and being an RA at school (on campus job). she also admitted she was feeling that I wasn't putting enough work into the relationship, and admittedly I suppose I was getting rather complacent because every time I asked her to do something it failed due to scheduling. 

so she broke up with me without even having the decency to arrange an in person meet up because if she saw me she would give in and coward out, but she knows what she wants and she wants to end it. fine. whatever. I'm upset but It is what it is I guess. fast forward a few days and now she is messaging me apologizing saying she messed up and wants to get back together. I have anxiety and a lot of stress as it is and I usually have the "I don't play games" kind of attitude. but I don't know what I should do. I know it's hard to give solid advice to strangers, but what would you guys do? she had it set in her mind that she wanted to break up and now I think she's just upset and wants instant gratification and to revert back to that comfort zone.

Can you give me the gist of the text in a nutshell?
<bot>: girlfriend broke up with me over text message and seemed adamant that it was the right decision. 3 days later she regrets it and wants me to take her back and I'm torn.
