How do you handle being the other woman? is it hard for you and any tips?

The only time it happened, when I discovered that I was the other woman, I broke up immediately.
It caused me profound grief that lasted at least six months, during which I did some pretty crazy and stupid things, like trying to find someone like him who was single. Eventually I realised this was impossible (no two people are alike... why hadn't I known that?) and self destructive, and started to accept the loss.
I carried a flame in my heart for him for many years.
Eventually I learned enough to finally get truly over it.
I bumped into him by accident once. He and she had broken up sometime later. He had married another woman, who was unbearably jealous and possessive, that had one child together, and live in abject misery. He even tried to tempt me back in. Needless to say, I told him, "I'm so sorry for your misery, Peter, but as we make our beds, so we must lie in them." I gave him a kiss on the cheek and left. There were tears flowing down his cheeks.

Remember these days when you are being cheated on.

It wouldn't be hard for me to be the other woman, it would be IMPOSSIBLE! I wouldn't be able to cause that kind of pain to his wife and children. I wouldn't be able to be so shallow, selfish and cruel. And when I'm with a man, I want to be with a good man, not a cheater. even if some day he did leave his wife for me, He would just end up cheating on me! I want a man who is all mine, I don't want to have to share. I want him to be there for me, to hold me & sleep next to me every night. to be with me on the holidays. to be able to hold my hand, kiss me & go out on dates in public, to proudly tell everyone I'm his woman. in an affair NONE of these things are possible. plus I'm a jealous person at times, so knowing he went to bed with another woman at night would kill me inside. of course this is all supposing that I'd be with a married man, which I wouldn't!! It would only cause agony to everyone involved, especially you and his wife! it would also be very lonely, you'd only be able to spend time with him when he is able to get away, able to make an excuse for where he is, he won't be able to send the night, or go out for dinners, because he'll be home with his wife. Being a misstress would entail a lot of waiting and lonliness. I personally couldn't handle it, I mean you wouldn't even really be able to call & talk to him on the phone. ity would all be so secretive, it would be based on lies. I would never want that. and I think if you look deep inside yourself you know you don't want any of this either, so if you haven't done it yet, please don't, it would not be worth it. You want a man who can be yours, all yours. and he never will be. also ask yourself, would you really want a man who would risk hurting his wife so badly by cheating on her?

Wish I had nice suggestions for "the other woman", but because "the other woman" has the potential to ruin others lives, I only ask if "the other woman" is proud our her choice, and that "the other woman" can sleep well at night.
I suspect as "the other woman" one holds very little remorse for what they are doing and likely are sitting right there saying "mind your own business you old cow".
