I am going through a breakup, we were together for five years I am heartbroken
I'm so sorry to hear that. I was together with my wife for 7 years when she left me so I know your pain.
it's horrible. I know you felt the same way. I just want this terrible feeling to be over.
It takes awhile for it to be over. Find a hobby to take your mind off of it. It helps to ease the pain.
