I was dating a girl briefly for about a month and we eventually fizzled out. She stopped responding to any of my snaps and stopped initiating conversation with me. It's been about 2 weeks since we stopped talking and I've been wanting to try again one more time. I feel like I might have messed up by not following up with her after out last date but I did not do so because I felt she was not interested anymore. Is there anything I should do or say in order to try and restart talking to her without being awkward?
