Can be friends with ex boylfriend??????????????????

I'm one or the only one who can't be friends with ex boyfriend,
just a simple matter,
prevent new problems,
I'm not sure.

Can make friends with anyone
Friends opened a new life,,
jokes and laughter,
share a story,
anything ..

If only a very bad mood,
open all the memories of the past,

Mood that always brings us discuss why and who causes our relationship ended,
everything is not fair,
to anyone......

I choose away from you,
Do not force me to be your friend,
I hope you understand.
