Also, I just found it interesting that no one I talked to said "you have to telll her.". Just got me thinking why the common reaction was not that one. Never had
much reason to think about it before this year.
I haven't had time to read all the posts, but here is someone who is saying that you have to tell her. It may be in your best interests not to, as then it's easier to pawn your abusive BPD partner off on her lover, but that doesn't make it right. Wouldn't YOU want to know? I certainly would and no amount of rationalizations makes it OK to keep the information from me. I don't care if my husband cheated but had decided never to do it again. I don't care if it would disrupt my life. I don't care if it would put me in a financially awkward position. I don't want to live a lie and I have the right to the information I need to make these decisions. In my opinion, it is cowardly to keep this information to yourself. It's also condescending. Who is anyone to decide for the other person that it is better for them to continue livigng a lie, for whatever reason, than to make a decision based on truth? Who are you to decide that it would be less disruptive for her, or less upsetting, or financially better, or better for the kids? Some people feel that having parents who live a life of lies and affairs is worse than having divorced parents and they are entitled to that opinion and entitled to act on it even if someone else disagrees about what is in the cheated partner's and kids best interest. Different people have different opinions of what financial viability is. And they have a right to assert their opinions in their own life and not have decisions made for them through withholding of information. The other person has a right to know and not to live a life of lies. Sure, they might choose to stay. But then they are choosing with full knowledge of their situation. I often read of women who are devastated by their spouse's affair and have that devastation compounded by the humiliation of knowing that someone could have enlightened them but chose not to. I think it's selfish to keep it to yourself, so that you can feel good about "taking the high road" and not being vindictive. Just because it feels satisfying to get a bit of revenge on your own cheating partner does not mean telling the other person is wrong - there are plenty of good reasons to tell her. And I haven't even mentioned STDs. Again, now that you have this information, who are you to decide that she shouldn't have the information she needs to stay healthy? You can decide for yourself if you want to continue a sexual relationship with a cheater, knowing the risks. Is it really fair to decide for someone else that the risks are reasonable? They deserve the chance to decide and while it's certainly not easy, I think you are obligated to provide information that could have a deadly impact on someone else's life. How would you feel if you later found out the other partner who was being cheated on got HIV because they were clueless of their cheating spouse's activities? How would you feel if it was you in that position, instead of your wife's lover's wife? Sure, maybe the other person knows, but maybe they don't and I think it is better to err on the side of telling them. If they do know, then you're not really disrupting anything by repeating the information (although I'm sure discussing it would be upsetting, do you really think that telling someone who already knows is going to somehow change their mind about what they have decided to do about it?), and if they don't then you are basically respecting their right to be an autonomous individual and make their own decisions about their lives, decisions based on reality and not lies kept from the person based on your judgement of what is in their best interestes.
