<human>: Give me a shortened version of the text

So English is not my native language so I´ll try to explain this simply.
I´m on a long distance relationship with my girlfriend. We stayed seven months without seeing each other, during this period I did not cheat her, didnt have any sexual contact at all apart from just masturbating. 
So I went to see her for new years eve and stayed with her one month. After 15 days more or less she started to bleed even though she wasn´t on period anymore. At the begining we thought it was nothing so she only went to see a doctor now and has just found she has the bacteria Chlamydia trachomatis. We are not together anymore cause I had to come back home to study again and she´s accusing me of cheating.

It seems like I gave her that, but I think I already have that somehow. But for me it seems strange because if I already had that I should have given to her already cause we saw each other before as well.

So I´m really confused now. I´m calling the doctor now to scheduled th exams for me as well, most likely I got that as well. At least I´ve done the HIV exam on december so I´m sure I dont have that.

Is there anyway I got clamydia apart from sexual contact? and also, maybe she´s lying and she cheated on me? I´m really lost.
<bot>: In a LDR and after I met my GF after six months she has been diagnosed with clmayidia and since then she´s accusing me of cheating
