Umm, we all slip up in our choice of words sometimes. The opinion you expressed there was entirely valid - and probably not offensive to anyone either. The choice of words for how you expressed it was probably spontaneous and, as is easily done, probably came across with different connotations & linkage-to-context than you meant it, and it hurt.
These things happen. Friends hurt each other - the close we are, the easier it is for that to happen, because we place more value on the opinion of those friends, and we also have let most of our guards down, are more vulnerable.
You realised the hurt you caused & apologised, I'm confident that'll heal that matter.

Slinking off might protect you & others from further verbal slip-ups and hurt, but will also deprive you of our company and us of yours. I can't see that as a good thing, so please come back once you've regained your equilibrium? (*hugs* offered)
