So im gonna start with a little bit of background information: Be me, 22 y/o male in the middle of his in-firm training (takes 3 years), who has been in a relationship with his first gf for almost 6 years. Fly to the USA for 4 weeks as a part of your training. Get your ass dumped via whatsapp after you´ve been there for 1 week because of another guy that she met (he gave her a ride from our hometown to the city where she studies for the last 1 1/2 years). Get messages like "Cant i be a little bit happy?" or "You havent cared about me in our relationship". Be sad as fuck, eat like once a day, no sleep because of jetlag + fucked up mentality. Cant enjoy the time you have there because you cant get a clear minute. Come back home after 4 weeks.

Thats where im gonna start. Of course she wanted to talk to me about everything and at the time i was abroad i also wanted to know why, but as i returned back home after 4 weeks full of shit i was so done with her. I didnt want to speak to her or ever see her again, even if the time we had together was beautiful and i loved her more than anything else. I can understand if you break up if you have the feeling that it just doesnt work anymore, but not like this, not after almost 6 years. Was that what i deserved? To be dumped like someone she barely knew and didnt care about? I felt so worthless for about 2-3 months. Without my friends and my parents i probably wouldnt be where i am right now and i spent the first few weeks talking with them about what happend so i could process it. 

Almost everybody told me that i should not answer her messages or calls anymore, and that was just what i did. Of course she kept writing me, but i just ignored her. After a few months it started getting better and i didnt have to think about her all the time.

Now, after almost 1 year (all this took place in June 2018), she is blaming me that her conscience is bothering her and that she has to think about me alot, that she cant concentrate on her studies and that the relationship with her new bf suffers from her having to think about me. So basically she states that all this happened because i didnt want to settle things with her, but i really dont give a damn about what she thinks or how she feels now. AITA for this?
