Thank you for your reply nacirema!
Of course I have been in situations where I had to deak with grief before.
I meant more the "extra" thing poly adds to the package.
I have a relationship> ok.
I have a crush on someone I have just started seeing> ok.
I am heartbroken because one partner leaves>
Maybe I am the only person who feels this is confusing.... (I am NOT talking morals here, just heart and feelings.)
