I \[F19\] guess this more of a vent than asking advice. So, my ex \[M26\] which I broke up about 2 weeks ago from distance (moved abroad) threatened to block me if I texted him again. We separated loving each other and he was calling me every day to express his love still even if we broke up. I was against this since we are not together and told him I am trying to move on. He has insecurities so he straight up asked if I'm seeing someone. I said I went on a brief date (a short walk just talking. No physical stuff) just to clear my mind. He got mad af blaming me for moving too fast, disrespecting our relationship. I said nothing physical happened but obv will happen at some point with someone that isn't him. Bc that's how just life goes. He took this the wrong sense and blamed me and stopped texting. After 2 days I saw him texting one of my reddit accounts that he does not know who I am. (It was a fake account) I couldnt stop myself from replying like I am somebody else (I know this is toxic but i just needed to hear what he had to say about me to someone else). He said his ex (me) f\*\*ked someone on new years and posted stories on IG with a dude and that I broke his heart. He just told terrible things about me indicating I am a slut who f\*\*ked him over. (Btw he is currently on tinder/bumble swiping himself for dates). Ofc bc I didn't wanna expose myself I didn't say much in his favor and just cried. Everything he told was a lie. I never f\*\*ked anyone after him or had bad intentions. Never posted a story with a guy. Basically, he talking false s\*\*t about me. I know I hurt him but what else I can do? Any advice on what to feel/do?
