He deleted me for months and then added me back on Snapchat?

We were good friends and then I found out that he had deleted me on Snapchat so I deleted him back and yesterday I got a notification saying he added me by username. Why would he delete me and then add me after months.

So I didn't add him back but anyone can contact me, so he said that a creeper with my name had added him and he deleted me thinking I was the other one. I knew this was bullsh*t because he also deleted my sister and I just said "cool story.."
