Leeann,
sorry to hear that, but have u considered it properly? Talk to him, open up, and let him know ur feeling, probably it helps!
planning for a wedding is though, all of us here are going through it. No doubts sometimes arguement will arise due to different opinions and viewpoints, e.g. why need this, why need that etc. And when problem arises, thoughts like calling off the wedding will appear, however, think carefully, is that what u really want? or say it in a fit of moment? Please think over it carefully, we are already this far..
whatever it might happen, please do remember you still have us as ur friend and i am sure we will stand by u, be it happiness or ..
