Everyone is busy at times and cannot spare a moment to text or call someone. If your crush messages you saying he is busy, you should answer with something like "okay, I will chat to you later." If he continues to insist he can't converse through text for days, something is wrong. Cut him off and move on. The most effective ways of responding to a person who is busy are: quickly texting back and forth several times a day; sending flowers weekly or sometimes even monthly; making reservations together online or via phone; and turning conversations into dates (if that's what you want). Busy people have very little time for anything else but that doesn't mean they don't want to be friends with you. All you have to do is ask them out directly or suggest meeting up for coffee/lunch/dinner/go bowling/etc. And remember, if they refuse then there's no harm done in asking again here or on Facebook. Also note that some people may be busy not telling you everything about themselves so don't take it personally if they seem evasive about their life. Sometimes we hide parts of our personality for various reasons. Finally, don't take it seriously if someone keeps insisting he's too busy for friendship - after all, nobody is perfect!
