Depends on the girl.
If a guy responds to your texts quickly while he is playing a game it means he is very interested in you.
Don't wait on him. If he's not answering his texts, it could be that he is not interested.
Well I'm a guy, and when a girl texts me i usually like it when their interested in what i do. hope this helps!
If a guy texts back quickly, it could mean he is interested in the conversation and values your communication. He might also be available and eager to continue the conversation.
if it is sweet messages no but if it was just hi or something yes
Within a day or so
he likes you not as a friend i say go out with him
If I had to guess, he probably isn't interested in you, but he wants to LOOK like he's interested in you. This probably means he's trying to make another girl jealous.
He is tiered or bored of your good night texts OR he isn't bothered / interested or maybe his phone has run out of credit / battery.
He is flirting with you and seems to be interested in you.
When a man responds to your text messages he must be interested in You but get to know him first then if you want ask them out
