As an old fogey (of 58 years) there are times when I want to despair about young people!
Texting might be a cheap and convenient way of sending routine messages between people but it's a utterly pathetic way of trying to understand someone's feeling. (It's so easy to read something into a text which was never intended by the person who sent it, simply because you can't hear the intonation in their voice).
Do NOT text him! PHONE him and have a real CONVERSATION with him! You'll be able to find out where you stand with him far more easily in a short phone call than you ever could in a thousand texts!
