My ex boyfriend broke up with me 3 months ago, and recently he reached out for my birthday. We texted the next 4 days and then he started sending me snapchats. We haven’t texted in a week now yet he still sends me 1-2 snapchats a day that I don’t respond to. He didn’t send me any during the breakup, so Why now? Is he testing the waters to open communication again? Should I continue to ignore them?
