@JacobSartoriousGurl Well...see I went through this but I know it feels somewhat different to everyone...
But what I did was distract myself from him, if you haven't listened to SOUR by Olivia Rodrigo, I highly recommend giving that a try because her songs made a lot of sense to me and the positions he put me through.
What the songs did was fuel the rage and sadness that I had still bottle up inside and pretty soon that emotion turned into courage and determination, now I'm on a mission to make myself a better person and reach full potential, that way you show little lover by what he missed out on...but never, and I mean NEVER go back to him if he played you in the first place.
Trust me it won't end well.
