what should i do if someone are not texting you .. and your attracted to the guy ?what is the best move .. to make him fall
I tend to agree with Rock, but without knowing more, it's tough to give advice. One thing for sure, is that you can't make anyone fall for you. They are either interested or they aren't.
Your topic is "confused by his behavior" which leads me to think you've had interactions with him before and he just stopped texting for some reason?
If that's the case, it would depend on how long you've chatted in the past and how long it's been since you've heard from him. Also have you made your intentions clear, let him know you like him or are attracted to him? Has he done the same?
If it's someone you just met, then as Rock said, it would appear he's not interested and moving on would be best. Why waste your time on someone who's not responding to you?
