I used my best friend to satisfy a craving
In what way did you use him?
I told him I loved him and he believed me and loved me then I left him and used him
You should find another way to satisfy your cravings, using your best friend is wrong. If you use people they will eventually want nothing to do with you.
Why are you being a prick?
I just think it's wrong to use your best friend like that. I'm sure that really hurt his feelings and you should never do it again.
