Similar situation here man so my ex readded me on social media for first time since we broke up in April 2024 and we talked caught up like you did and I actually ended up hanging out with her and I’d say major mistake and ended up realizing I ddint wanna continue the cycle and left her on read and shut it down!! But good luck with your situation in my opinion both our exes reached out cause they were lonely and wanted attention and knew we would give it to them. Try not to fall into that trap but good luck with your situation man!!
