Best Friend/Boyfriend thing

So I had a guy best friend and we were best friends for 5 years... Eventually I started falling for him and stuff and he felt the same way so we tried being together... We've been together, on and off for over a year now...

I'm getting really tired of this and I want him out of my life... He never has time for me and we never get to see each other so we text but he takes hours and days to reply and it feels terrible... He also posts happy birthday messages to other girls and its starting to irritate me coz its happening nearly every week... But I'm overly attached and have no idea how to get over him... I'm also in my final year of school and in the middle of writing trial exams... This year is really important for me as I need to excel in order to get into med school...

So here's where my Eveys and all come into the picture ... I need advice and help on how to get over this guy as soon as possible and stop thinking about him while I'm trying to study

Thank you guys ♥️🍫
