<human>: Can you give me a shortened version of the text?

Me 27m. Long story short, she (25f) moved back to her home country for what was supposed to be 3 months. She broke up with me because I couldn't come visit as often b/c her stay ended up being longer and longer and longer. One of her friends just sent me an email telling me she's been seeing this guy since her first day back. She even blew me off when I came to visit to see him. I had no clue there was another guy until now. I've been pretty messed up thinking that everything was my fault until now. I guess she dumped it on me and made me feel like shit. Her parents lectured me because I couldn't afford to come see her as often as they wanted, lecturing me on how I was raised. We were together for 2.5 years Question I have is, should I tell this guy about her habits? Tell her parents? Thanks!
<bot>: girlfriend moved back to homecountry for short period, cheated on me, broke up and blamed everything on me. Should I tell the guy and her parents?
