Weird Snapchat Guy

I often talk to random guys on Snapchat, they quick ad me and I accept. Sometime late last year I talked to this guy, and though the chats sometimes got spicy I still liked talking to him. Everything was fine for maybe 5 months until one day he just didn’t text. Over the course of maybe a month (around April-May) I texted him every couple of days asking where he went etc. He never ended up answering, so I blocked him. Months passed and its now October and I got added by a random guy. I added him back and as we were talking, I can't shake the feeling that it's the same guy. The way they talk is similar, their time zones are the same, and they have the SAME name. The only difference I noticed was he said he was 5 years older which is weird. I also asked him if we talked before and he said, "Nope. I doubt it." The reason I'm obsessing over this is I was so lost with him yk? Like we spoke every day, so suddenly not talking was hard for me to get used to. And when I did, he came back..
