NEW RELATIONSHIP ADIVCE

Kayli
Hi! I’ve never posted on here before I’ve always been very shy! But I have a question that I need to ask a group of women. 
So I’m in a new relationship and I’m not really sure if it necessary to delete old flings from my phone. I don’t want to bring it up with him because then it might sound like I’m hiding something, which I’m not. But do I go through and purge out old contacts and messages? What about on social media such as Snapchat and twitter? I hope this doesn’t sound like a juvenile question but I’m really curious. 
Thank you!!
