The truth is you could slit my throat and with my one last gasping breath I'd apologize for bleeding on your shirt
Does this sound at all like something you might say?
A) Yes
B) No
If you answered A, you apologize too much.
If you found this offensive, I apolo...wait, no, not going to do that this time.
I definitely used to apologize too much. Various reasons. Definitely insecurity for some of the times. If it is someone you know, you likely wish to keep them holding a high opinion of you. Someone you don't, well, then there's more options. Regardless, you can definitely apologize too much. How much is too much is hard to say, previous posts on when is "good" help some.
