I was supposed to visit my ex who lives far away a while ago. We planned the trip and everything was all set... but I missed the flight. I apologized but she was angry and said I had broken her heart and to never contact her again.

I felt terrible and couldn't let it go. For a couple months I didn't contact her at all. But then I sent her a postcard from the new city I moved to that just said "forgive me?" on the back. I got no response. I texted her after that a couple times just saying I really didn't mean to miss the flight and that I missed her. But she didn't get back to me.

Now every now and then I text her a song title that reminds me of her maybe once a month or so. Is it creepy to continue sending her little texts and notes every few months or so? Should I just call it quits? I know she loved me very much at one point...
