Re: my fiance is cheating on me??
First, you make him uncomfortable by being intrusive, then you see some sent emails and conclude that he is cheating on you. Why on earth do you think you have the right to invade someone's privacy? Would you like him going through your stuff? Well I dont know about you but a lot of people dont like other people poking their nose into their personal space.
Woman, you are being overly demanding. Everybody needs their space. That guy is not married, engagement doesnt do magic, if he is into these online things it will take a while before he starts getting into that 'committed' mindset.
Considering your thought process, perhaps you two arent a good match - find someone who will sit and stand when and where you say. If you want to be with a man, get over your insecurity. Its disturbing.
