Is I lose weight could it make him like me?

losin wieght or changin your apperance probably wont make him like you if he already doesnt and if it does thats not what you want anyway because then he only likes you for your loooks and when someone likes you it should be for your personality. Also as you have said trust means allot between you both , why dont you tell him how you feel when he talks about other girls around you and that you cant help it because your feelings are really strong if your both really that close he should understand. However if this guy doesnt like you him stoppin talkin about other girls is not goin to stop you bein upset it may help but if you cant be with him you'll probably still be upset.If your really sure this guy only wants to be friends with you maybe you should just try and move on no matter how hard it is. Maybe spend time apart or talk about it with him first , but if the situation is makin you upset you either have to find a way of gettin together with him or movin on. Good luck
