Sorry for asking but do you mean school, school or university/college?? If it's school I take it that your both very young. If this is the case then I would suggest just moving on and getting over it and putting it down to immaturity on his behalf. If this is meant to be it will be. Given that your are so young (by the sounds of it) just put it behind you and enjoy your freedom as a single girl. Trust me - there is no rush to become tied to one man. Go out, have fun, possibly date another guy and consider yourself lucky that you didn't marry at this stage in your life. As for him - I think he has a lot of growing up to do as evidenced by his actions - planning to get married, breaking up then wanting to make up and being obsessive about contacting you. He needs to work out what he wants and only time will sort that one out. So given that your both at the same school and sometimes in the same classes I can see that no contact is near to impossible. Just be polite, meet and greet a bit of small talk and that's it. Do not engage in heavy conversation at this stage. You both need time out to clear your heads. All the best.
