If your fiance was already caught texting sexual messages to a female, your fiance is the one who pushed ' you ' away. don't allow yourself to be manipulated by others, you know you deserve better for yourself so why hurt yourself by staying with them. being single would even be a step up.. but if you do decide to break off the engagement, be on your gaurd because the man will most likely tell you exactly what you want to hear - which will be only temperary. Love yourself!
