How Long to Wait Until You Know You’ve Been Ghosted

Ok so I never post on here but this has been driving me crazy the past few days!

Alright so I met this guy online, (he’s 22 and I’m 18 in college) I know it sounds sketchy trust me I was unsure of it but it’s been great (until now). I met him on this chatting site and we got along super well and exchanged snapchats. He lived states away and I didn’t tell him where I lived or anything so I was safe! But he was amazing, we sent pictures back and forth (nothing at all sexual or like nudes or anything) and talked every day for almost 3 months! It was great he was so nice and kind! We both caught feelings and told each other and like it was awesome but sucked since we were so far away but I really like him and thought who knows what the future holds!

Anyway, fast forward! On Saturday I was working and then took a nap, I woke up to some snaps from him and he said he was going to Canada to visit family (he’s done that before) and he wouldn’t be able to talk for the rest of the night. Then he also said his phone was acting so weird and he was getting a new one on Monday, and he might be getting a new Snapchat so I shouldn’t be worried if he added me on a new one. I thought this was weird but didn’t think anything of it. But now he deleted me on Snapchat (on Saturday) and hasn’t added me again. I know it’s only been a few days and I probably seem psycho but I’m on my period and it always makes me overreact, but do you think I’ve been ghosted or is it too soon? I don’t have any of his other info to talk to him I just had his snap so I might be acting crazy but I’m kinda upset and freaking out a little. Help!
