tell him to quit it!

I wouldn;t worry about regaining his respect.. he isn;t capable of it... his behaviour is bordering on creepy. And there is a small chance too that he is actually making fun of you. But, you say he freaks out if you don;t reply to his texts? Isn't that a bit weird? Why are you even answering his texts? I'm sorry, but you are making a bit of a fool of yourself, I think. This guy is just having cheap thrills at your expense.. do not reply to another text from him... and if you do, and if you think thee is a future relationship here, then prepare yourself for a disappointment

He is younger a randy teenager and yer he is using you sounds like he prob had a bet on with his mates to see if he could get you in bed by summers over as he don't text so much now your back at school.
Your to old for him he is immature and it shows when he looses his temper when you don't text straight away.
You don't want his respect if he has a temper now imagine what he would be like if you did go out with him he is playing you get rid of him and meet some one your own age who wants to talk about you and other things not just sex.
Next time he texts say i think its time we called it a day say im bored of the sex talk i have a life i don't need this sorry and good bye, if he cares about you he will say sorry if he doesn't he will loose his temper and get nasty because he didn't get his way if he makes out your fidget just say no i just don't like you lol and the only person with the respect here is you and that respect is for yourself don't let him take that away from you.
Good luck.

sounds like he is bored.
