<human>: Basically, I screwed up.  I tried to come off as someone I wasn't to impress her and it ultimately backfired and things fell through after the 3rd date.  She basically just one day out of the blue I guess had it and blocked my number, Facebook, and Twitter.  She wasn't completely perfect herself, but what I did was wrong/worse nonetheless.

I told the story to a friend who offered me her phone/Facebook to send her one last message apologizing and wishing her luck in the future.  I don't want her back at all nor do I want a response, but it would make me feel so much better to get it off my chest.  Is that weird?

We spoke for a good 2 months almost daily before this happened.

Can you summarize the given text in a few sentences?
<bot>: Don't know if apologizing to girl after she blocked me for a screw up would be a big no-no or not.  I don't want her back but it would make me feel better to get it off of my chest.
