2 best friends going out....should i tell her?

[beachguy in thongs]

Any friend who fucks your ex-girl 2 day after you broke up is not your friend.

Ouch!

That hurts. The last time I asked about a best friend of mine (at my H.S. 10-year reunion), the answer was, "Nobody's heard of him".

When we were sixteen, I slept with his girlfriend, while I had a girlfriend.

I guess that under your rules, I shouldn't worry about him, anymore.
