My single friend started an affair with a married man a few months ago. At the time I tried to warn her off but she was adament that it was just a bit a fun, she knew he wouldn't leave his wife and kids and she accepted that. She said that she was happier having a casual no-strings fling rather than have to deal with the problems she has encountered in the past with real relationships (she has had a few bad 'uns!). He gave her the usual 'I'm not happy, just staying for the sake of the kids' talk and I gave her the 'they all say that, he's just using you, you (and his wife) will end up getting hurt' talk.
Now the inevitable has happened! She's fallen for him big time and he's talking about leaving his wife. From what my friend has told me he has actually taken steps towards doing this, so it doesn't seem to be 'just' talk.
I'm really worried about my friend getting badly hurt. Obviously I feel bad for the wife and children (I've been cheated on myself) but my friend is my friend and I love her. Has anyone had any experience of an affair developing into a real relationship? Does it always end in tears for the 'other woman'?
