Mobiles have a lot to answer for dont they? I am sorry you are having this heartache, texts and the like are so easily misconstrued too, and sometimes not, but they are definitely a secret, exciting form of communication. Men are weak honey, always will be where ladies are concerned, i dont know what advice i can give, its a helpless situation and it will go downhill from here unless you both talk, i used to think married people who have affairs were unhappy in their marriage, but i dont know why they do it. Please talk to him darling and get this in the open, it doesnt bode well im afraid, but the very best of luck it goes the way you want it to and all is ok.
