Just ended no contact…no reply

Hello all! My girlfriend of over a year broke up with me about 5 weeks ago. I instantly went no contact. She doesn’t believe that ex’s can talk after a breakup and didn’t try to contact me at all. I posted lots of good things on Facebook that I was doing and new pictures of myself etc, basically went out and lived my life. After a month I still missed her and wanted her in my life. We’re 20 and she is in the Air Force so was gone a lot of the relationship but we were incredibly committed. Certain issues between us led her to dump me, issues I thought could be resolved. Anyway, I texted her Wednesday basically saying “Hey it’s (my name)!” Then stated something that had made me think of her and wished her well. I used smileys and was just friendly. I got radio silence. To be honest I didn’t expect a reply but still. Where do I go from here with nc? Thanks in advance!
