Why Did My Crush Suddenly Stop Texting Me?

Everyone has the same problem,, honestly if he stop textes you send ONE message just to reel back the conversation and after he replies(if he does) don't talk to him until he replies again. Make sure when you text him though its something flirtatious so when you don't reply and hes forced to again he'll be on anticipation
- say "hey cutey"  or "you looked nice today"

Maybe they are already in a relationship.

Perhaps he is busy. Try sending him one or two texts and see if he responds. If he doesn't respond after a couple texts then I would say he has lost interest.

He is texting someone else or someone else is texting him......the best to you
