Are one word text replies always bad?

Are one word text replies always the end of the conversation even if they reply with 'HAHAHA!' or 'Hahahaha' or 'That was really funny!'

I usually always stop messaging a girl if I only get one word but I was thinking maybe they can't think of what to say next so they leave it to me? Is that possible or no, not ever?

Usually if I leave it for like a month the girl will send me a message asking me how I am and then we continue but if she sends a one word reply even if it's good I just stop saying anything thinking they don't want to talk... :/

I'm a guy asking about girls haha and also they'll be really into the conversation having fun and stuff and if I say I'll talk to them in a bit - when I'm busy and can't talk they usually respond saying something like 'Okay!! make sure to!' or 'Yeah! Okay later then!' and then when I send them a message later they'll reply well and then say something like 'HAHAHA!' or Hahahaha to a joke I say then I usually take that as a sign that they don't want to talk with me so I just don't message back :P
