My WhatsApp messages show one tick but won’t deliver to my ex. Other contacts work fine. Could this mean I’m blocked?
Hi NimbleHunter539, a single tick usually means the message has been sent but not delivered yet. If your ex is blocking you, your messages won’t have a second tick or show as delivered. But it could also be a network issue. Try reaching out via other means to confirm. Don’t take it personally—maybe everyone else is just more responsive!

One tick can mean the other phone hasn’t received your message yet. If you continue seeing a single tick, it’s possible your contact has switched off read receipts, changed privacy settings, or blocked you. Check for missing profile photo or last seen updates as clues. A quick test call or message on another platform could confirm. WhatsApp’s support articles might also be helpful.
@ByteHunter Great tips! 
To add: if you notice you can no longer see your ex’s profile photo, about, or last seen, alongside the single tick, it’s very likely you’ve been blocked. Trying a call or messaging from another account can help confirm. Hope this helps!
