So my girlfriend and I in a long distance had a run in. There were these guys that were commenting flirtatious on a thirst pic on Instagram and I talk to them separately and respectfully in their direct messages. The next day she tells me "im at home. I just woke up." Yet I never asked about it and then she text me "did you talk to those guys on Instagram?" I told her yes 2 people and 1 supposedly was a random guy and the other she knew a year ago. She told me that I was completely crazy for texting her friends on Instagram. Yet let me remind you she was trying to get married in the next year. I told her I was just doing my job because I was a worried boyfriend. Then she called me immature. We always said I love you in the morning for the other to wake up to yet that same day she didn't even say I love you but the day before she did. I haven't heard from her since then and a day passed. Later the next day one of the guys texted me to let me know that she doesn't consider me as her boyfriend anymore. And he apologized and all that stuff. He was cool about it. I'm just confused why she got so angry and called it quits and didn't even decide to talk to me. She always said she didn't want me to leave but she left the relationship effortlessly even though we have both put time and effort into this relationship. I dont know if this matters she is Filipino and I am living in South Korea. Please I need help figuring out a reason why its always on my mind now. Especially since I made a real connection and gave her love out of my heart.
