change??

so everyone changes at one stage or another rite??no 1 stays the same we all grow up and mature but what happens when you ur dream or rather the person you thought was your dream guy at the time turn into an arogant arsehole??
this has happened to me, me and joel were dating a good six months ago it was a messy break up boths of us still liking eachother but having no choice to break up due to other matters!!but anyway we stayed friends throughout but all of a sudden he strikes up conversation and we get txting agen and then meet up today...and wow has he changed and not for the better he made me feel horrible he was no longer this sweet caring guy who you could talk to about anything and always feel comfortable no matter what and now he's this rude arrogaunt person who doesn't have a nice thing to say and only form of communication was to put me down all day i can certainly say my confidence has been knocked quite a fair bit since today but i think it was just the shock of how much things have changed i went home feeling hurt today and he didn't even care i hope karma comes around and bites him because he is certainly no longer my mac dreamy im really disappointed he was way more attractive wen he was nice!i feel sorry for him he had sucha great personality but now i don't know what happens its amazing what change can do to ppl!!!
