Got really good grades better than I expected and have an offer to go to Durham University which is about an hour and half away from home but my boyfriend hates it and has been nagging me not to go away for uni he is a bit clingy and doesnt like me talking to other guys even though I have no intention of cheating on him or when I do go to uni but he doesnt see that he says he will dump me if I accept my offer or he said he will move up closer to be near me I mean dont want him to move either its like I want to least enjoy myself at uni and socialise what can I do to reassure him
