what can i do mi bfr **** mi close frn

I think I know what you tried to ask. What word has four letters, refers to something that two people might do together which would interfere with a friendship, but will always be blanked out with asterisks here?

Your best friend "diddled" your close friend? I think that's what you said.

Anyway, it depends on what exactly you mean. If you mean that you found that someone who you thought was a true friend, was "itersecting" with someone that you thought was your own lover, then that would mean that neither of them are what you thought they were.

Tell them that you know what they did, that they insulted and mistreated you by doing so, and that therefore neither of them are to be a part of your life going forward.

Just my suggestion, based on my values, and my guess about what you posted.
