I accidentally offended a girl I like, what to do?

We used to chat online very other night. When we met in person, we would talk on and on, making tons of inside jokes all the way. She'd laugh at all my bad puns and small slip-ups. And aside from that, there was always that little something that mad it feel more special. But I messed it up one night.

She was teasing me about some other person I used to like, and so I made a little joke about her being jealous. After that, the playful talk turned to curt talk, and she would keep avoiding me.

I've apologized more times than you can count on a crowd's hands. I tried to make it a little more personal by writing an apology letter with a small flower on her desk. It still didn't seem to work, as the friendship never did come back.

I just don't know what to do. I really do still like her, but I'm in a really bad spot. Any help?

or:Just tell her that you are sorry and you didn't mean it, make the apology seem heartfelt but not sappy tell her that you like her still don't make her jealous that'll make it worse and when you are done with the heartfelt apology give her a comforting hug

or:I'm going to be very honest. It sounds like you made an honest mistake and you obviously didn't mean for it to turn this way. You have apologized to her many many times, I don't understand why she isn't responding. Try To apologize one last time and if she doesn't respond after that then stop. She obviously does not care anymore so do not waste your time. There is a reason why this happened. You don't want someone who gets mad at small things like these, specially if you've been having to apologize many times.
