Regret is kissing my *** what do I do?

So my bf or well now ex has been ignoring me for sometime like there was literally nothing going on but he would always look back at me with this look as if someone had died he would never talk to me and I would text him he would never answer I eventually couldn't take it anymore Cuz well im not a mind reader and told him he needs to break up with me I tell him this all over text I then later on tell him In person saying he needs to break up with me Cuz I'm not the person to do so and he goes idk I go well Idk he goes idk what do you want me to say I go hb your thoughts he goes bannas I go bannas are lovely and it ends there so yesterday night I took it into my own hands and called him of coarse he didn't answer so I left him a voice message saying it is over and how I can't take it anymore I thought I would feel better but I just feel regret and crushed and heart broken
