Can y'all help (ex- relationship issues)

I broke up with my bf on new years tho year i don't care much rn , my friends keep saying how he was and what all wrong things he did with me
Ps storytime so he was actually cute and pretty we like the same things we had like same favourite things songs colours everything (actually we first talked was because we had the same phone like colour and verything) it was cute I love the feeling of talking to him I loved that I had someone to talk to me i guess I was just filling the gap of loneliness because tbh idt he actually cared or lisnted becuz often i would get interrupted but I didn't mind cuz he can also talk bout his day right? I used to love his ambitions his dreams i wanted to be part of them but who would've imagined he would give the same reason to break up i regret acting non chalant on the day we broke up the crying I did later i should've just done it in front of him .
Though idc anymore , I have him blocked on everything everywhere, but few weeks back i met him while meeting my best friend (m) who is also his best friend lol funny right , that when we talked after months he kept asking me to unblock telling me don't I miss him cuz he does but I avoided it these days he started prank calling me ? When I asked why he is like i wanted to hear your voice then one day gave me piece of his chocolate and disappear today I was head banging to get my hair look good he randomly while walking by played with my hair ,i didn't notice until he went away the. When I was talking with my friend he was nearby talking to some girls but he kept sneaking glances at me I could sense it ig
But idk anymore becuz of his best friend I have kinda suffered idk he asked me to keep our relationship secret i didn't mind I said sure if that's what you want why didnt I think about what I want why did i always go with his flow it's like I've forgotten what being me was
His best friend
So uhh his best friend rough topic she is very clingy so some of our friendgrp already had an idea about me and him dating then one day i introduced him to my teammate (I wish i didn't but not that it matters now? )
Then in a month they started hanging out going to concerts I asked him bout it he said she's just a friend and even back bitched bout her and other female friends and then she started hugging him longer holding his hands taking him away then it started to affect me alot I felt like I was overthinking situation then she started sitting in his lap I felt I was the weird one in the grp for not seeing this as funny then I saw their photo the head on her thighs them goin on just duo hangouts am I overthinking??? Or was it some sort of cheating?? He kept ignoring my messages the replies become late then...
